In some embodiments, the specific network traffic associated with completion of the first operation by the SUT comprises one or more of a first HTTP message sent from the SUT to the test server and a second HTTP message sent from the test server to the SUT. The foregoing, together with other features and embodiments, will become more apparent upon referring to the following specification, claims, and accompanying drawings.
The present disclosure is described in conjunction with the appended figures:
Various embodiments are generally directed to techniques for automated software testing, such as by verifying operations are complete based on user interface and/or network traffic indications, for instance. Some embodiments are particularly directed to utilizing a network sniffer to detect specific network traffic to verify completion of network requests and/or responses associated with an operation included in a workflow for performance by a software under test (SUT). As will be described in more detail below, in many embodiments, the detection of specific network traffic may be used to accurately time operation durations and/or efficiently perform workflows to evaluate the SUT. These and other embodiments are described and claimed.
Some challenges facing automated software testing include lack of a reliable indication via the user interface (UI) that a step or operation has completed. For example, a ‘busy’ or ‘completed’ indication may appear too briefly to consistently detect. In another example, a value or element may be inaccessible via the UI, such as in a canvas container (i.e., a container for holding various drawing elements such as lines, shapes, text, frames containing other elements, and the like). In yet another example, raw data (e.g., network data) is not intended to be viewed in the UI presentation layer. These and other issues can hinder the ability to achieve accurate timings, consistent flow control, and/or data validation. Additionally, utilizing fixed delays between UI operations in an effort to allow operations to complete before advancing in a workflow fails to resolve these issues. For example, fixed delays may skew timings due to the timer being stopped based on a fixed delay and not based on the application (e.g., SUT) completing the operation. In another example, fixed delays may cause untimely and inefficient workflow implementation (i.e., untimely and inefficient execution of a workflow), such as when operations complete before the fixed delay concludes, yet implementation of the workflow does not continue until after the fixed delay. Conversely, an operation that takes longer than the fixed delay can cause implementation of a workflow to fail or run differently than intended (e.g., skew results). Relying on validation processes performed after completion of a workflow, rather than in real time, to detect improper operation also results in untimely and inefficient workflow implementation. These and other factors may result in software testing systems with excessive delays, limited applicability, and poor adaptability. Such limitations can drastically reduce the usability and accuracy of the software testing systems, contributing to inefficient systems, devices, and techniques. Still further, utilizing image validation to determine whether operations are complete before advancing in a workflow has several limitations and drawbacks. Some of the limitations of image validation include but are not limited to the following. Completion indicators appearing and disappearing before they can be detected by the UI automation tool. Visual inconsistencies preventing image validation from even being an option. Slowness in verification. Failure to verify based on image variation. False verification due to imprecise image verification criteria, which may be due to attempts to avoid failed verification.
In light of the above challenges, several embodiments described herein include software test system (STS) that utilizes a network sniffer to determine when operations of a SUT initiated by a user interface automation tool (UIAT) have completed. In various embodiments, a network sniffer may comprise software for intercepting, analyzing, and/or logging communications for application-layer protocols (e.g., FTP, SMTP, POP3, IMAP, HTTPS, HTTP and SSH). In many embodiments, the use of sniffed network traffic with UI automation may be integrated into the workflow in real time (or near-real time). These and other features may allow the STS to precisely record timings and avoid adding fixed delays for the workflow to consistently function. For example, sniffing of network traffic in real time for specific network traffic associated with completion of an operation by the SUT can be used to determine when the operation is finished/completed regardless of whether there is an UI indication of the operation's completion and/or detection thereof, which cannot be achieved if network traffic is replayed and/or only analyzed after workflow completion. In many embodiments, accurate and real-time determination of completion times allows exact and reliable timing of operations (e.g., for end-user actions in a UI application) and/or quick and consistent execution of a workflow to test software, leading to improved workflows. The improved workflow for UI-driven test automation may apply to functional, automation, and/or performance testers. Further, one or more STSs described herein can facilitate comprehensive validation of live test data, such as by using all content returned for verification.
In several embodiments, network traffic may be recorded and/or monitored. For instance, network traffic, or characteristics thereof, may be stored in one or more computer-readable media (e.g., one or more of main memory, disk memory, flash memory, caches, registers, system memory, random access memory). In many such instances, the one or more computer-readable media may be collectively referred to as a test digest. In various embodiments, captured network traffic (e.g., traffic stored in the test digest) may be used to validate the accuracy of sent and received data in real-time. In one or more embodiments, the process of integrating sniffed network traffic with UI automation tools can significantly improve one or more of flow control, timing, and validation. In some embodiments, one or more portions of SUT may be implemented by a test server. For example, the SUT may include an application hosted by the test server and/or an interface for interacting with the application, such as via a network. In some such examples, the interface for interacting with the application may be via a network access application (e.g., a web browser) implemented by a client.
More generally, accurate timings (e.g., how long an operation takes to complete) may be important for software performance testing and engineering. Quick and consistent flow control can be crucial when automating software testing. In various embodiments, flow control may refer to the steps that a UIAT uses to perform the desired operations against the SUT (e.g., application under test). Several embodiments may additionally, or alternatively, verify and/or validate request and/or response data. Further, one or more embodiments may allow a workflow to be modified based on the data that is received in a client-network intercommunication, which would not be possible if simulated traffic that was designated before testing began was used.
In some embodiments, the UIAT may be used to interact with a client UI that sends requests to an application server. A network sniffer may be used to determine when to progress through a workflow based on various criteria, such as data transmission and/or data validation (e.g., with the application server). In several such embodiments, the application server may execute the SUT, such as in response to commands provided by the UIAT (e.g., via a browser application). In other such embodiments, the STS may execute the SUT. In some embodiments, the application server may be the same or similar to a test server. In many embodiments, the STS may simulate one or more aspects (e.g., external data/interactions) for testing purposes. For example, STS may include, or be built upon, a logic platform, such as a computing platform/framework/environment for statistical analyses, that allows actual and/or simulated communication/interaction with external agents. In such examples, one or more aspects of the network, application server, and/or test server may be simulated.
Many embodiments herein may protect the STS from advancing through a UI-workflow too quickly (e.g., test a result of an operation before the operation has completed) by identifying and/or waiting for predetermined network traffic to complete. Additionally, this can ensure consistent and reliable actions (e.g., start/stop operations, data detection, data monitoring, etcetera). Several embodiments herein may prevent excessive delays to wait for necessary network requests to complete, thereby reducing the amount of time it takes to implement a workflow (i.e., execution of a workflow). For instance, fixed delays may have a safety factor of buffer time built-in to prevent premature operations. Various embodiments herein may detect changes to network traffic profiles driven from the Client, which can reduce the need of external input (e.g., user input) for the validation of tests.
In these and other ways, components described here may provide techniques to improve user interface automation, resulting in increased efficiency, decreased computational cost, and/or reduced resource requirements, in an accurate, dynamic, and scalable manner, resulting in several technical effects and advantages over conventional computer technology, including increased capabilities and improved adaptability. In various embodiments, one or more of the aspects, techniques, and/or components described herein may be implemented in a practical application via one or more computing devices, and thereby provide additional and useful functionality to the one or more computing devices, resulting in more capable, better functioning, and improved computing devices. Further, one or more of the aspects, techniques, and/or components described herein may be utilized to improve the technical field of software testing, user interface automation, timing, workflow implementation, and/or the like.
In several embodiments, components described herein may provide specific and particular manners of determining when operations (e.g., an operation initiated by the UIAT and executed by the SUT) are completed. In multiple embodiments, the specific and particular manner of determining when an operation is complete may include detecting specific network traffic associated with completion of the operation (i.e., network completion data). In many embodiments, one or more of the components described herein may be implemented as a set of rules that improve computer-related technology by allowing a function not previously performable by a computer that enables an improved technological result to be achieved. For example, the function allowed may include integrating network sniffing with UI automation to reliably determine when an operation has completed.

Further, these manipulations are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. However, no such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein that form part of one or more embodiments. Rather, these operations are machine operations. Useful machines for performing operations of various embodiments include machines selectively activated or configured by a routine stored within that is written in accordance with the teachings herein, and/or include apparatus specially constructed for the required purpose. Various embodiments also relate to apparatus or systems for performing these operations. These apparatuses may be specially constructed for the required purpose or may include a general-purpose computer. The required structure for a variety of these machines will appear from the description given.
In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of embodiments of the technology. However, it will be apparent that various embodiments may be practiced without these specific details. The figures and description are not intended to be restrictive.
The ensuing description provides example embodiments only, and is not intended to limit the scope, applicability, or configuration of the disclosure. Rather, the ensuing description of the example embodiments will provide those skilled in the art with an enabling description for implementing an example embodiment. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the technology as set forth in the appended claims.
Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details.

In other instances, well-known circuits, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments.
Also, it is noted that individual embodiments may be described as a process which is depicted as a flowchart, a flow diagram, a data flow diagram, a structure diagram, or a block diagram. Although a flowchart may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be re-arranged. A process is terminated when its operations are completed but could have additional operations not included in a figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination can correspond to a return of the function to the calling function or the main function.
Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details.

The intention is to cover all modifications, equivalents, and alternatives within the scope of the claims.
Systems depicted in some of the figures may be provided in various configurations. In some embodiments, the systems may be configured as a distributed system where one or more components of the system are distributed across one or more networks in a cloud computing system.
Data transmission network 100 may also include computing environment 114. Computing environment 114 may be a specialized computer or other machine that processes the data received within the data transmission network 100. Data transmission network 100 also includes one or more network devices 102. Network devices 102 may include client devices that attempt to communicate with computing environment 114. For example, network devices 102 may send data to the computing environment 114 to be processed, may send signals to the computing environment 114 to control different aspects of the computing environment or the data it is processing, among other reasons. Network devices 102 may interact with the computing environment 114 through a number of ways, such as, for example, over one or more networks 108. As shown in
In other embodiments, network devices may provide a large amount of data, either all at once or streaming over a period of time (e.g., using event stream processing (ESP), described further with respect to
Data transmission network 100 may also include one or more network-attached data stores 110. Network-attached data stores 110 are used to store data to be processed by the computing environment 114 as well as any intermediate or final data generated by the computing system in non-volatile memory. However in certain embodiments, the configuration of the computing environment 114 allows its operations to be performed such that intermediate and final data results can be stored solely in volatile memory (e.g., RAM), without a requirement that intermediate or final data results be stored to non-volatile types of memory (e.g., disk). This can be useful in certain situations, such as when the computing environment 114 receives ad hoc queries from a user and when responses, which are generated by processing large amounts of data, need to be generated on-the-fly. In this non-limiting situation, the computing environment 114 may be configured to retain the processed information within memory so that responses can be generated for the user at different levels of detail as well as allow a user to interactively query against this information.
Network-attached data stores may store a variety of different types of data organized in a variety of different ways and from a variety of different sources. For example, network-attached data storage may include storage other than primary storage located within computing environment 114 that is directly accessible by processors located therein. Network-attached data storage may include secondary, tertiary or auxiliary storage, such as large hard drives, servers, virtual memory, among other types. Storage devices may include portable or non-portable storage devices, optical storage devices, and various other mediums capable of storing, containing data. A machine-readable storage medium or computer-readable storage medium may include a non-transitory medium in which data can be stored and that does not include carrier waves and/or transitory electronic signals. Examples of a non-transitory medium may include, for example, a magnetic disk or tape, optical storage media such as compact disk or digital versatile disk, flash memory, memory or memory devices. A computer-program product may include code and/or machine-executable instructions that may represent a procedure, a function, a subprogram, a program, a routine, a subroutine, a module, a software package, a class, or any combination of instructions, data structures, or program statements. A code segment may be coupled to another code segment or a hardware circuit by passing and/or receiving information, data, arguments, parameters, or memory contents. Information, arguments, parameters, data, etc. may be passed, forwarded, or transmitted via any suitable means including memory sharing, message passing, token passing, network transmission, among others. Furthermore, the data stores may hold a variety of different types of data. For example, network-attached data stores 110 may hold unstructured (e.g., raw) data, such as manufacturing data (e.g., a database containing records identifying products being manufactured with parameter data for each product, such as colors and models) or product sales databases (e.g., a database containing individual data records identifying details of individual product sales).
The unstructured data may be presented to the computing environment 114 in different forms such as a flat file or a conglomerate of data records and may have data values and accompanying time stamps. The computing environment 114 may be used to analyze the unstructured data in a variety of ways to determine the best way to structure (e.g., hierarchically) that data, such that the structured data is tailored to a type of further analysis that a user wishes to perform on the data. For example, after being processed, the unstructured time stamped data may be aggregated by time (e.g., into daily time period units) to generate time series data and/or structured hierarchically according to one or more dimensions (e.g., parameters, attributes, and/or variables). For example, data may be stored in a hierarchical data structure, such as a ROLAP OR MOLAP database, or may be stored in another tabular form, such as in a flat-hierarchy form.
Data transmission network 100 may also include one or more server farms 106. Computing environment 114 may route select communications or data to the one or more sever farms 106 or one or more servers within the server farms. Server farms 106 can be configured to provide information in a predetermined manner For example, server farms 106 may access data to transmit in response to a communication. Server farms 106 may be separately housed from each other device within data transmission network 100, such as computing environment 114, and/or may be part of a device or system.
Server farms 106 may host a variety of different types of data processing as part of data transmission network 100. Server farms 106 may receive a variety of different data from network devices, from computing environment 114, from cloud network 116, or from other sources. The data may have been obtained or collected from one or more sensors, as inputs from a control database, or may have been received as inputs from an external system or device. Server farms 106 may assist in processing the data by turning raw data into processed data based on one or more rules implemented by the server farms. For example, sensor data may be analyzed to determine changes in an environment over time or in real-time.
Data transmission network 100 may also include one or more cloud networks 116. Cloud network 116 may include a cloud infrastructure system that provides cloud services. In certain embodiments, services provided by the cloud network 116 may include a host of services that are made available to users of the cloud infrastructure system on demand Cloud network 116 is shown in
While each device, server and system in
Each communication within data transmission network 100 (e.g., between client devices, between a device and connection management system 150, between servers 106 and computing environment 114 or between a server and a device) may occur over one or more networks 108. Networks 108 may include one or more of a variety of different types of networks, including a wireless network, a wired network, or a combination of a wired and wireless network. Examples of suitable networks include the Internet, a personal area network, a local area network (LAN), a wide area network (WAN), or a wireless local area network (WLAN). A wireless network may include a wireless interface or combination of wireless interfaces. As an example, a network in the one or more networks 108 may include a short-range communication channel, such as a Bluetooth or a Bluetooth Low Energy channel A wired network may include a wired interface. The wired and/or wireless networks may be implemented using routers, access points, bridges, gateways, or the like, to connect devices in the network 114, as will be further described with respect to
Some aspects may utilize the Internet of Things (IoT), where things (e.g., machines, devices, phones, sensors) can be connected to networks and the data from these things can be collected and processed within the things and/or external to the things. For example, the IoT can include sensors in many different devices, and high value analytics can be applied to identify hidden relationships and drive increased efficiencies. This can apply to both big data analytics and real-time (e.g., ESP) analytics. IoT may be implemented in various areas, such as for access (technologies that get data and move it), embed-ability (devices with embedded sensors), and services. Industries in the IoT space may automotive (connected car), manufacturing (connected factory), smart cities, energy and retail. This will be described further below with respect to
As noted, computing environment 114 may include a communications grid 120 and a transmission network database system 118. Communications grid 120 may be a grid-based computing system for processing large amounts of data. The transmission network database system 118 may be for managing, storing, and retrieving large amounts of data that are distributed to and stored in the one or more network-attached data stores 110 or other data stores that reside at different locations within the transmission network database system 118. The compute nodes in the grid-based computing system 120 and the transmission network database system 118 may share the same processor hardware, such as processors that are located within computing environment 114.
As shown in
Although network devices 204-209 are shown in
As noted, one type of system that may include various sensors that collect data to be processed and/or transmitted to a computing environment according to certain embodiments includes an oil drilling system. For example, the one or more drilling operation sensors may include surface sensors that measure a hook load, a fluid rate, a temperature and a density in and out of the wellbore, a standpipe pressure, a surface torque, a rotation speed of a drill pipe, a rate of penetration, a mechanical specific energy, etc. and downhole sensors that measure a rotation speed of a bit, fluid densities, downhole torque, downhole vibration (axial, tangential, lateral), a weight applied at a drill bit, an annular pressure, a differential pressure, an azimuth, an inclination, a dog leg severity, a measured depth, a vertical depth, a downhole temperature, etc. Besides the raw data collected directly by the sensors, other data may include parameters either developed by the sensors or assigned to the system by a client or other controlling device. For example, one or more drilling operation control parameters may control settings such as a mud motor speed to flow ratio, a bit diameter, a predicted formation top, seismic data, weather data, etc. Other data may be generated using physical models such as an earth model, a weather model, a seismic model, a bottom hole assembly model, a well plan model, an annular friction model, etc. In addition to sensor and control settings, predicted outputs, of for example, the rate of penetration, mechanical specific energy, hook load, flow in fluid rate, flow out fluid rate, pump pressure, surface torque, rotation speed of the drill pipe, annular pressure, annular friction pressure, annular temperature, equivalent circulating density, etc. may also be stored in the data warehouse.
In another example, another type of system that may include various sensors that collect data to be processed and/or transmitted to a computing environment according to certain embodiments includes a home automation or similar automated network in a different environment, such as an office space, school, public space, sports venue, or a variety of other locations. Network devices in such an automated network may include network devices that allow a user to access, control, and/or configure various home appliances located within the user's home (e.g., a television, radio, light, fan, humidifier, sensor, microwave, iron, and/or the like), or outside of the user's home (e.g., exterior motion sensors, exterior lighting, garage door openers, sprinkler systems, or the like). For example, network device 102 may include a home automation switch that may be coupled with a home appliance. In another embodiment, a network device can allow a user to access, control, and/or configure devices, such as office-related devices (e.g., copy machine, printer, or fax machine), audio and/or video related devices (e.g., a receiver, a speaker, a projector, a DVD player, or a television), media-playback devices (e.g., a compact disc player, a CD player, or the like), computing devices (e.g., a home computer, a laptop computer, a tablet, a personal digital assistant (PDA), a computing device, or a wearable device), lighting devices (e.g., a lamp or recessed lighting), devices associated with a security system, devices associated with an alarm system, devices that can be operated in an automobile (e.g., radio devices, navigation devices), and/or the like. Data may be collected from such various sensors in raw form, or data may be processed by the sensors to create parameters or other data either developed by the sensors based on the raw data or assigned to the system by a client or other controlling device.
In another example, another type of system that may include various sensors that collect data to be processed and/or transmitted to a computing environment according to certain embodiments includes a power or energy grid. A variety of different network devices may be included in an energy grid, such as various devices within one or more power plants, energy farms (e.g., wind farm, solar farm, among others) energy storage facilities, factories, homes and businesses of consumers, among others. One or more of such devices may include one or more sensors that detect energy gain or loss, electrical input or output or loss, and a variety of other efficiencies. These sensors may collect data to inform users of how the energy grid, and individual devices within the grid, may be functioning and how they may be made more efficient.
Network device sensors may also perform processing on data it collects before transmitting the data to the computing environment 114, or before deciding whether to transmit data to the computing environment 114. For example, network devices may determine whether data collected meets certain rules, for example by comparing data or values calculated from the data and comparing that data to one or more thresholds. The network device may use this data and/or comparisons to determine if the data should be transmitted to the computing environment 214 for further use or processing.
Computing environment 214 may include machines 220 and 240. Although computing environment 214 is shown in
Computing environment 214 can communicate with various devices via one or more routers 225 or other inter-network or intra-network connection components. For example, computing environment 214 may communicate with devices 230 via one or more routers 225. Computing environment 214 may collect, analyze and/or store data from or pertaining to communications, client device operations, client rules, and/or user-associated actions stored at one or more data stores 235. Such data may influence communication routing to the devices within computing environment 214, how data is stored or processed within computing environment 214, among other actions.
Notably, various other devices can further be used to influence communication routing and/or processing between devices within computing environment 214 and with devices outside of computing environment 214. For example, as shown in
In addition to computing environment 214 collecting data (e.g., as received from network devices, such as sensors, and client devices or other sources) to be processed as part of a big data analytics project, it may also receive data in real-time as part of a streaming analytics environment. As noted, data may be collected using a variety of sources as communicated via different kinds of networks or locally. Such data may be received on a real-time streaming basis. For example, network devices may receive data periodically from network device sensors as the sensors continuously sense, monitor and track changes in their environments. Devices within computing environment 214 may also perform pre-analysis on data it receives to determine if the data received should be processed as part of an ongoing project. The data received and collected by computing environment 214, no matter what the source or method or timing of receipt, may be processed over a period of time for a client to determine results data based on the client's needs and rules.
The model can include layers 302-314. The layers are arranged in a stack. Each layer in the stack serves the layer one level higher than it (except for the application layer, which is the highest layer), and is served by the layer one level below it (except for the physical layer, which is the lowest layer). The physical layer is the lowest layer because it receives and transmits raw bites of data, and is the farthest layer from the user in a communications system. On the other hand, the application layer is the highest layer because it interacts directly with a software application.
As noted, the model includes a physical layer 302. Physical layer 302 represents physical communication, and can define parameters of that physical communication. For example, such physical communication may come in the form of electrical, optical, or electromagnetic signals. Physical layer 302 also defines protocols that may control communications within a data transmission network.
Link layer 304 defines links and mechanisms used to transmit (i.e., move) data across a network. The link layer manages node-to-node communications, such as within a grid computing environment. Link layer 304 can detect and correct errors (e.g., transmission errors in the physical layer 302). Link layer 304 can also include a media access control (MAC) layer and logical link control (LLC) layer.
Network layer 306 defines the protocol for routing within a network. In other words, the network layer coordinates transferring data across nodes in a same network (e.g., such as a grid computing environment). Network layer 306 can also define the processes used to structure local addressing within the network.
Transport layer 308 can manage the transmission of data and the quality of the transmission and/or receipt of that data. Transport layer 308 can provide a protocol for transferring data, such as, for example, a Transmission Control Protocol (TCP). Transport layer 308 can assemble and disassemble data frames for transmission. The transport layer can also detect transmission errors occurring in the layers below it.
Session layer 310 can establish, maintain, and manage communication connections between devices on a network. In other words, the session layer controls the dialogues or nature of communications between network devices on the network. The session layer may also establish checkpointing, adjournment, termination, and restart procedures.
Presentation layer 312 can provide translation for communications between the application and network layers. In other words, this layer may encrypt, decrypt and/or format data based on data types known to be accepted by an application or network layer.
Application layer 314 interacts directly with software applications and end users, and manages communications between them. Application layer 314 can identify destinations, local resource states or availability and/or communication content or formatting using the applications.
Intra-network connection components 322 and 324 are shown to operate in lower levels, such as physical layer 302 and link layer 304, respectively. For example, a hub can operate in the physical layer, and a switch can operate in the link layer. Inter-network connection components 326 and 328 are shown to operate on higher levels, such as layers 306-314. For example, routers can operate in the network layer and network devices can operate in the transport, session, presentation, and application layers.
As noted, a computing environment 314 can interact with and/or operate on, in various embodiments, one, more, all or any of the various layers. For example, computing environment 314 can interact with a hub (e.g., via the link layer) so as to adjust which devices the hub communicates with. The physical layer may be served by the link layer, so it may implement such data from the link layer. For example, the computing environment 314 may control which devices it will receive data from. For example, if the computing environment 314 knows that a certain network device has turned off, broken, or otherwise become unavailable or unreliable, the computing environment 314 may instruct the hub to prevent any data from being transmitted to the computing environment 314 from that network device. Such a process may be beneficial to avoid receiving data that is inaccurate or that has been influenced by an uncontrolled environment. As another example, computing environment 314 can communicate with a bridge, switch, router or gateway and influence which device within the system (e.g., system 200) the component selects as a destination. In some embodiments, computing environment 314 can interact with various layers by exchanging communications with equipment operating on a particular layer by routing or modifying existing communications. In another embodiment, such as in a grid computing environment, a node may determine how data within the environment should be routed (e.g., which node should receive certain data) based on certain parameters or information provided by other layers within the model.
As noted, the computing environment 314 may be a part of a communications grid environment, the communications of which may be implemented as shown in the protocol of
Communications grid computing system (or just “communications grid”) 400 also includes one or more worker nodes. Shown in
A control node may connect with an external device with which the control node may communicate (e.g., a grid user, such as a server or computer, may connect to a controller of the grid). For example, a server or computer may connect to control nodes and may transmit a project or job to the node. The project may include a data set. The data set may be of any size. Once the control node receives such a project including a large data set, the control node may distribute the data set or projects related to the data set to be performed by worker nodes. Alternatively, for a project including a large data set, the data set may be received or stored by a machine other than a control node (e.g., a Hadoop data node).
Control nodes may maintain knowledge of the status of the nodes in the grid (i.e., grid status information), accept work requests from clients, subdivide the work across worker nodes, coordinate the worker nodes, among other responsibilities. Worker nodes may accept work requests from a control node and provide the control node with results of the work performed by the worker node. A grid may be started from a single node (e.g., a machine, computer, server, etc.). This first node may be assigned or may start as the primary control node that will control any additional nodes that enter the grid.
When a project is submitted for execution (e.g., by a client or a controller of the grid) it may be assigned to a set of nodes. After the nodes are assigned to a project, a data structure (i.e., a communicator) may be created. The communicator may be used by the project for information to be shared between the project code running on each node. A communication handle may be created on each node. A handle, for example, is a reference to the communicator that is valid within a single process on a single node, and the handle may be used when requesting communications between nodes.
A control node, such as control node 402, may be designated as the primary control node. A server, computer or other external device may connect to the primary control node. Once the control node receives a project, the primary control node may distribute portions of the project to its worker nodes for execution. For example, when a project is initiated on communications grid 400, primary control node 402 controls the work to be performed for the project in order to complete the project as requested or instructed. The primary control node may distribute work to the worker nodes based on various factors, such as which subsets or portions of projects may be completed most efficiently and in the correct amount of time. For example, a worker node may perform analysis on a portion of data that is already local (e.g., stored on) the worker node. The primary control node also coordinates and processes the results of the work performed by each worker node after each worker node executes and completes its job. For example, the primary control node may receive a result from one or more worker nodes, and the control node may organize (e.g., collect and assemble) the results received and compile them to produce a complete result for the project received from the end user.
Any remaining control nodes, such as control nodes 404 and 406, may be assigned as backup control nodes for the project. In an embodiment, backup control nodes may not control any portion of the project. Instead, backup control nodes may serve as a backup for the primary control node and take over as primary control node if the primary control node were to fail. If a communications grid were to include only a single control node, and the control node were to fail (e.g., the control node is shut off or breaks) then the communications grid as a whole may fail and any project or job being run on the communications grid may fail and may not complete. While the project may be run again, such a failure may cause a delay (severe delay in some cases, such as overnight delay) in completion of the project. Therefore, a grid with multiple control nodes, including a backup control node, may be beneficial.
To add another node or machine to the grid, the primary control node may open a pair of listening sockets, for example. A socket may be used to accept work requests from clients, and the second socket may be used to accept connections from other grid nodes). The primary control node may be provided with a list of other nodes (e.g., other machines, computers, servers) that will participate in the grid, and the role that each node will fill in the grid. Upon startup of the primary control node (e.g., the first node on the grid), the primary control node may use a network protocol to start the server process on every other node in the grid. Command line parameters, for example, may inform each node of one or more pieces of information, such as: the role that the node will have in the grid, the host name of the primary control node, the port number on which the primary control node is accepting connections from peer nodes, among others. The information may also be provided in a configuration file, transmitted over a secure shell tunnel, recovered from a configuration server, among others. While the other machines in the grid may not initially know about the configuration of the grid, that information may also be sent to each other node by the primary control node. Updates of the grid information may also be subsequently sent to those nodes.
For any control node other than the primary control node added to the grid, the control node may open three sockets. The first socket may accept work requests from clients, the second socket may accept connections from other grid members, and the third socket may connect (e.g., permanently) to the primary control node. When a control node (e.g., primary control node) receives a connection from another control node, it first checks to see if the peer node is in the list of configured nodes in the grid. If it is not on the list, the control node may clear the connection. If it is on the list, it may then attempt to authenticate the connection. If authentication is successful, the authenticating node may transmit information to its peer, such as the port number on which a node is listening for connections, the host name of the node, information about how to authenticate the node, among other information. When a node, such as the new control node, receives information about another active node, it will check to see if it already has a connection to that other node. If it does not have a connection to that node, it may then establish a connection to that control node.
Any worker node added to the grid may establish a connection to the primary control node and any other control nodes on the grid. After establishing the connection, it may authenticate itself to the grid (e.g., any control nodes, including both primary and backup, or a server or user controlling the grid). After successful authentication, the worker node may accept configuration information from the control node.
When a node joins a communications grid (e.g., when the node is powered on or connected to an existing node on the grid or both), the node is assigned (e.g., by an operating system of the grid) a universally unique identifier (UUID). This unique identifier may help other nodes and external entities (devices, users, etc.) to identify the node and distinguish it from other nodes. When a node is connected to the grid, the node may share its unique identifier with the other nodes in the grid. Since each node may share its unique identifier, each node may know the unique identifier of every other node on the grid. Unique identifiers may also designate a hierarchy of each of the nodes (e.g., backup control nodes) within the grid. For example, the unique identifiers of each of the backup control nodes may be stored in a list of backup control nodes to indicate an order in which the backup control nodes will take over for a failed primary control node to become a new primary control node. However, a hierarchy of nodes may also be determined using methods other than using the unique identifiers of the nodes. For example, the hierarchy may be predetermined, or may be assigned based on other predetermined factors.
The grid may add new machines at any time (e.g., initiated from any control node). Upon adding a new node to the grid, the control node may first add the new node to its table of grid nodes. The control node may also then notify every other control node about the new node. The nodes receiving the notification may acknowledge that they have updated their configuration information.
Primary control node 402 may, for example, transmit one or more communications to backup control nodes 404 and 406 (and, for example, to other control or worker nodes within the communications grid). Such communications may be sent periodically, at fixed time intervals, between known fixed stages of the project's execution, among other protocols. The communications transmitted by primary control node 402 may be of varied types and may include a variety of types of information. For example, primary control node 402 may transmit snapshots (e.g., status information) of the communications grid so that backup control node 404 always has a recent snapshot of the communications grid. The snapshot or grid status may include, for example, the structure of the grid (including, for example, the worker nodes in the grid, unique identifiers of the nodes, or their relationships with the primary control node) and the status of a project (including, for example, the status of each worker node's portion of the project). The snapshot may also include analysis or results received from worker nodes in the communications grid. The backup control nodes may receive and store the backup data received from the primary control node. The backup control nodes may transmit a request for such a snapshot (or other information) from the primary control node, or the primary control node may send such information periodically to the backup control nodes.
As noted, the backup data may allow the backup control node to take over as primary control node if the primary control node fails without requiring the grid to start the project over from scratch. If the primary control node fails, the backup control node that will take over as primary control node may retrieve the most recent version of the snapshot received from the primary control node and use the snapshot to continue the project from the stage of the project indicated by the backup data. This may prevent failure of the project as a whole.
A backup control node may use various methods to determine that the primary control node has failed. In one example of such a method, the primary control node may transmit (e.g., periodically) a communication to the backup control node that indicates that the primary control node is working and has not failed, such as a heartbeat communication. The backup control node may determine that the primary control node has failed if the backup control node has not received a heartbeat communication for a certain predetermined period of time. Alternatively, a backup control node may also receive a communication from the primary control node itself (before it failed) or from a worker node that the primary control node has failed, for example because the primary control node has failed to communicate with the worker node.
Different methods may be performed to determine which backup control node of a set of backup control nodes (e.g., backup control nodes 404 and 406) will take over for failed primary control node 402 and become the new primary control node. For example, the new primary control node may be chosen based on a ranking or “hierarchy” of backup control nodes based on their unique identifiers. In an alternative embodiment, a backup control node may be assigned to be the new primary control node by another device in the communications grid or from an external device (e.g., a system infrastructure or an end user, such as a server or computer, controlling the communications grid). In another alternative embodiment, the backup control node that takes over as the new primary control node may be designated based on bandwidth or other statistics about the communications grid.
A worker node within the communications grid may also fail. If a worker node fails, work being performed by the failed worker node may be redistributed amongst the operational worker nodes. In an alternative embodiment, the primary control node may transmit a communication to each of the operable worker nodes still on the communications grid that each of the worker nodes should purposefully fail also. After each of the worker nodes fail, they may each retrieve their most recent saved checkpoint of their status and re-start the project from that checkpoint to minimize lost progress on the project being executed.
The process may also include receiving a failure communication corresponding to a node in the communications grid in operation 506. For example, a node may receive a failure communication including an indication that the primary control node has failed, prompting a backup control node to take over for the primary control node. In an alternative embodiment, a node may receive a failure that a worker node has failed, prompting a control node to reassign the work being performed by the worker node. The process may also include reassigning a node or a portion of the project being executed by the failed node, as described in operation 508. For example, a control node may designate the backup control node as a new primary control node based on the failure communication upon receiving the failure communication. If the failed node is a worker node, a control node may identify a project status of the failed worker node using the snapshot of the communications grid, where the project status of the failed worker node includes a status of a portion of the project being executed by the failed worker node at the failure time.
The process may also include receiving updated grid status information based on the reassignment, as described in operation 510, and transmitting a set of instructions based on the updated grid status information to one or more nodes in the communications grid, as described in operation 512. The updated grid status information may include an updated project status of the primary control node or an updated project status of the worker node. The updated information may be transmitted to the other nodes in the grid to update their stale stored information.
Similar to in
Each node also includes a data store 624. Data stores 624, similar to network-attached data stores 110 in
Each node also includes a user-defined function (UDF) 626. The UDF provides a mechanism for the DMBS 628 to transfer data to or receive data from the database stored in the data stores 624 that are managed by the DBMS. For example, UDF 626 can be invoked by the DBMS to provide data to the GESC for processing. The UDF 626 may establish a socket connection (not shown) with the GESC to transfer the data. Alternatively, the UDF 626 can transfer data to the GESC by writing data to shared memory accessible by both the UDF and the GESC.
The GESC 620 at the nodes 602 and 620 may be connected via a network, such as network 108 shown in
DMBS 628 may control the creation, maintenance, and use of database or data structure (not shown) within nodes 602 or 610. The database may organize data stored in data stores 624. The DMBS 628 at control node 602 may accept requests for data and transfer the appropriate data for the request. With such a process, collections of data may be distributed across multiple physical locations. In this example, each node 602 and 610 stores a portion of the total data managed by the management system in its associated data store 624.
Furthermore, the DBMS may be responsible for protecting against data loss using replication techniques. Replication includes providing a backup copy of data stored on one node on one or more other nodes. Therefore, if one node fails, the data from the failed node can be recovered from a replicated copy residing at another node. However, as described herein with respect to
To initiate the project, the control node may determine if the query requests use of the grid-based computing environment to execute the project. If the determination is no, then the control node initiates execution of the project in a solo environment (e.g., at the control node), as described in operation 710. If the determination is yes, the control node may initiate execution of the project in the grid-based computing environment, as described in operation 706. In such a situation, the request may include a requested configuration of the grid. For example, the request may include a number of control nodes and a number of worker nodes to be used in the grid when executing the project. After the project has been completed, the control node may transmit results of the analysis yielded by the grid, as described in operation 708. Whether the project is executed in a solo or grid-based environment, the control node provides the results of the project in operation 712.
As noted with respect to
The ESPE may receive streaming data over a period of time related to certain events, such as events or other data sensed by one or more network devices. The ESPE may perform operations associated with processing data created by the one or more devices. For example, the ESPE may receive data from the one or more network devices 204-209 shown in
The engine container is the top-level container in a model that manages the resources of the one or more projects 802. In an illustrative embodiment, for example, there may be only one ESPE 800 for each instance of the ESP application, and ESPE 800 may have a unique engine name. Additionally, the one or more projects 802 may each have unique project names, and each query may have a unique continuous query name and begin with a uniquely named source window of the one or more source windows 806. ESPE 800 may or may not be persistent.
Continuous query modeling involves defining directed graphs of windows for event stream manipulation and transformation. A window in the context of event stream manipulation and transformation is a processing node in an event stream processing model. A window in a continuous query can perform aggregations, computations, pattern-matching, and other operations on data flowing through the window. A continuous query may be described as a directed graph of source, relational, pattern matching, and procedural windows. The one or more source windows 806 and the one or more derived windows 808 represent continuously executing queries that generate updates to a query result set as new event blocks stream through ESPE 800. A directed graph, for example, is a set of nodes connected by edges, where the edges have a direction associated with them.
An event object may be described as a packet of data accessible as a collection of fields, with at least one of the fields defined as a key or unique identifier (ID). The event object may be created using a variety of formats including binary, alphanumeric, XML, etc. Each event object may include one or more fields designated as a primary identifier (ID) for the event so ESPE 800 can support operation codes (opcodes) for events including insert, update, upsert, and delete. Upsert opcodes update the event if the key field already exists; otherwise, the event is inserted. For illustration, an event object may be a packed binary representation of a set of field values and include both metadata and field data associated with an event. The metadata may include an opcode indicating if the event represents an insert, update, delete, or upsert, a set of flags indicating if the event is a normal, partial-update, or a retention generated event from retention policy management, and a set of microsecond timestamps that can be used for latency measurements.
An event block object may be described as a grouping or package of event objects. An event stream may be described as a flow of event block objects. A continuous query of the one or more continuous queries 804 transforms a source event stream made up of streaming event block objects published into ESPE 800 into one or more output event streams using the one or more source windows 806 and the one or more derived windows 808. A continuous query can also be thought of as data flow modeling.
The one or more source windows 806 are at the top of the directed graph and have no windows feeding into them. Event streams are published into the one or more source windows 806, and from there, the event streams may be directed to the next set of connected windows as defined by the directed graph. The one or more derived windows 808 are all instantiated windows that are not source windows and that have other windows streaming events into them. The one or more derived windows 808 may perform computations or transformations on the incoming event streams. The one or more derived windows 808 transform event streams based on the window type (that is operators such as join, filter, compute, aggregate, copy, pattern match, procedural, union, etc.) and window settings. As event streams are published into ESPE 800, they are continuously queried, and the resulting sets of derived windows in these queries are continuously updated.
Within the application, a user may interact with one or more user interface windows presented to the user in a display under control of the ESPE independently or through a browser application in an order selectable by the user. For example, a user may execute an ESP application, which causes presentation of a first user interface window, which may include a plurality of menus and selectors such as drop down menus, buttons, text boxes, hyperlinks, etc. associated with the ESP application as understood by a person of skill in the art. As further understood by a person of skill in the art, various operations may be performed in parallel, for example, using a plurality of threads.
At operation 900, an ESP application may define and start an ESPE, thereby instantiating an ESPE at a device, such as machine 220 and/or 240. In an operation 902, the engine container is created. For illustration, ESPE 800 may be instantiated using a function call that specifies the engine container as a manager for the model.
In an operation 904, the one or more continuous queries 804 are instantiated by ESPE 800 as a model. The one or more continuous queries 804 may be instantiated with a dedicated thread pool or pools that generate updates as new events stream through ESPE 800. For illustration, the one or more continuous queries 804 may be created to model business processing logic within ESPE 800, to predict events within ESPE 800, to model a physical system within ESPE 800, to predict the physical system state within ESPE 800, etc. For example, as noted, ESPE 800 may be used to support sensor data monitoring and management (e.g., sensing may include force, torque, load, strain, position, temperature, air pressure, fluid flow, chemical properties, resistance, electromagnetic fields, radiation, irradiance, proximity, acoustics, moisture, distance, speed, vibrations, acceleration, electrical potential, or electrical current, etc.).
ESPE 800 may analyze and process events in motion or “event streams.” Instead of storing data and running queries against the stored data, ESPE 800 may store queries and stream data through them to allow continuous analysis of data as it is received. The one or more source windows 806 and the one or more derived windows 808 may be created based on the relational, pattern matching, and procedural algorithms that transform the input event streams into the output event streams to model, simulate, score, test, predict, etc. based on the continuous query model defined and application to the streamed data.
In an operation 906, a publish/subscribe (pub/sub) capability is initialized for ESPE 800. In an illustrative embodiment, a pub/sub capability is initialized for each project of the one or more projects 802. To initialize and enable pub/sub capability for ESPE 800, a port number may be provided. Pub/sub clients can use a host name of an ESP device running the ESPE and the port number to establish pub/sub connections to ESPE 800.
Publish-subscribe is a message-oriented interaction paradigm based on indirect addressing. Processed data recipients specify their interest in receiving information from ESPE 800 by subscribing to specific classes of events, while information sources publish events to ESPE 800 without directly addressing the receiving parties. ESPE 800 coordinates the interactions and processes the data. In some cases, the data source receives confirmation that the published information has been received by a data recipient.
A publish/subscribe API may be described as a library that enables an event publisher, such as publishing device 1022, to publish event streams into ESPE 800 or an event subscriber, such as event subscribing device A 1024a, event subscribing device B 1024b, and event subscribing device C 1024c, to subscribe to event streams from ESPE 800. For illustration, one or more publish/subscribe APIs may be defined. Using the publish/subscribe API, an event publishing application may publish event streams into a running event stream processor project source window of ESPE 800, and the event subscription application may subscribe to an event stream processor project source window of ESPE 800.
The publish/subscribe API provides cross-platform connectivity and endianness compatibility between ESP application and other networked applications, such as event publishing applications instantiated at publishing device 1022, and event subscription applications instantiated at one or more of event subscribing device A 1024a, event subscribing device B 1024b, and event subscribing device C 1024c.
Referring back to
ESP subsystem 800 may include a publishing client 1002, ESPE 800, a subscribing client A 1004, a subscribing client B 1006, and a subscribing client C 1008. Publishing client 1002 may be started by an event publishing application executing at publishing device 1022 using the publish/subscribe API. Subscribing client A 1004 may be started by an event subscription application A, executing at event subscribing device A 1024a using the publish/subscribe API. Subscribing client B 1006 may be started by an event subscription application B executing at event subscribing device B 1024b using the publish/subscribe API. Subscribing client C 1008 may be started by an event subscription application C executing at event subscribing device C 1024c using the publish/subscribe API.
An event block object containing one or more event objects is injected into a source window of the one or more source windows 806 from an instance of an event publishing application on event publishing device 1022. The event block object may generated, for example, by the event publishing application and may be received by publishing client 1002. A unique ID may be maintained as the event block object is passed between the one or more source windows 806 and/or the one or more derived windows 808 of ESPE 800, and to subscribing client A 1004, subscribing client B 806, and subscribing client C 808 and to event subscription device A 1024a, event subscription device B 1024b, and event subscription device C 1024c. Publishing client 1002 may further generate and include a unique embedded transaction ID in the event block object as the event block object is processed by a continuous query, as well as the unique ID that publishing device 1022 assigned to the event block object.
In an operation 912, the event block object is processed through the one or more continuous queries 804. In an operation 914, the processed event block object is output to one or more computing devices of the event subscribing devices 1024a-c. For example, subscribing client A 1004, subscribing client B 1006, and subscribing client C 1008 may send the received event block object to event subscription device A 1024a, event subscription device B 1024b, and event subscription device C 1024c, respectively.
ESPE 800 maintains the event block containership aspect of the received event blocks from when the event block is published into a source window and works its way through the directed graph defined by the one or more continuous queries 804 with the various event translations before being output to subscribers. Subscribers can correlate a group of subscribed events back to a group of published events by comparing the unique ID of the event block object that a publisher, such as publishing device 1022, attached to the event block object with the event block ID received by the subscriber.
In an operation 916, a determination is made concerning whether or not processing is stopped. If processing is not stopped, processing continues in operation 910 to continue receiving the one or more event streams containing event block objects from the, for example, one or more network devices. If processing is stopped, processing continues in an operation 918. In operation 918, the started projects are stopped. In operation 920, the ESPE is shutdown.
As noted, in some embodiments, big data is processed for an analytics project after the data is received and stored. In other embodiments, distributed applications process continuously flowing data in real-time from distributed sources by applying queries to the data before distributing the data to geographically distributed recipients. As noted, an event stream processing engine (ESPE) may continuously apply the queries to the data as it is received and determines which entities receive the processed data. This allows for large amounts of data being received and/or collected in a variety of environments to be processed and distributed in real time. For example, as shown with respect to
Aspects of the current disclosure provide technical solutions to technical problems, such as computing problems that arise when an ESP device fails which results in a complete service interruption and potentially significant data loss. The data loss can be catastrophic when the streamed data is supporting mission critical operations such as those in support of an ongoing manufacturing or drilling operation. An embodiment of an ESP system achieves a rapid and seamless failover of ESPE running at the plurality of ESP devices without service interruption or data loss, thus significantly improving the reliability of an operational system that relies on the live or real-time processing of the data streams. The event publishing systems, the event subscribing systems, and each ESPE not executing at a failed ESP device are not aware of or effected by the failed ESP device. The ESP system may include thousands of event publishing systems and event subscribing systems. The ESP system keeps the failover logic and awareness within the boundaries of out-messaging network connector and out-messaging network device.
In one example embodiment, a system is provided to support a failover when event stream processing (ESP) event blocks. The system includes, but is not limited to, an out-messaging network device and a computing device. The computing device includes, but is not limited to, a processor and a computer-readable medium operably coupled to the processor. The processor is configured to execute an ESP engine (ESPE). The computer-readable medium has instructions stored thereon that, when executed by the processor, cause the computing device to support the failover. An event block object is received from the ESPE that includes a unique identifier. A first status of the computing device as active or standby is determined. When the first status is active, a second status of the computing device as newly active or not newly active is determined. Newly active is determined when the computing device is switched from a standby status to an active status. When the second status is newly active, a last published event block object identifier that uniquely identifies a last published event block object is determined. A next event block object is selected from a non-transitory computer-readable medium accessible by the computing device. The next event block object has an event block object identifier that is greater than the determined last published event block object identifier. The selected next event block object is published to an out-messaging network device. When the second status of the computing device is not newly active, the received event block object is published to the out-messaging network device. When the first status of the computing device is standby, the received event block object is stored in the non-transitory computer-readable medium.
Different machine-learning models may be used interchangeably to perform a task. Examples of tasks that can be performed at least partially using machine-learning models include various types of scoring; bioinformatics; cheminformatics; software engineering; fraud detection; customer segmentation; generating online recommendations; adaptive websites; determining customer lifetime value; search engines; placing advertisements in real time or near real time; classifying DNA sequences; affective computing; performing natural language processing and understanding; object recognition and computer vision; robotic locomotion; playing games; optimization and metaheuristics; detecting network intrusions; medical diagnosis and monitoring; or predicting when an asset, such as a machine, will need maintenance.
Any number and combination of tools can be used to create machine-learning models. Examples of tools for creating and managing machine-learning models can include SAS® Enterprise Miner, SAS® Rapid Predictive Modeler, and SAS® Model Manager, SAS Cloud Analytic Services (CAS)®, SAS Viya® of all which are by SAS Institute Inc. of Cary, N.C.
Machine-learning models can be constructed through an at least partially automated (e.g., with little or no human involvement) process called training. During training, input data can be iteratively supplied to a machine-learning model to enable the machine-learning model to identify patterns related to the input data or to identify relationships between the input data and output data. With training, the machine-learning model can be transformed from an untrained state to a trained state. Input data can be split into one or more training sets and one or more validation sets, and the training process may be repeated multiple times. The splitting may follow a k-fold cross-validation rule, a leave-one-out-rule, a leave-p-out rule, or a holdout rule. An overview of training and using a machine-learning model is described below with respect to the flow chart of
In block 1104, training data is received. In some examples, the training data is received from a remote database or a local database, constructed from various subsets of data, or input by a user. The training data can be used in its raw form for training a machine-learning model or pre-processed into another form, which can then be used for training the machine-learning model. For example, the raw form of the training data can be smoothed, truncated, aggregated, clustered, or otherwise manipulated into another form, which can then be used for training the machine-learning model.
In block 1106, a machine-learning model is trained using the training data. The machine-learning model can be trained in a supervised, unsupervised, or semi-supervised manner In supervised training, each input in the training data is correlated to a desired output. This desired output may be a scalar, a vector, or a different type of data structure such as text or an image. This may enable the machine-learning model to learn a mapping between the inputs and desired outputs. In unsupervised training, the training data includes inputs, but not desired outputs, so that the machine-learning model has to find structure in the inputs on its own. In semi-supervised training, only some of the inputs in the training data are correlated to desired outputs.
In block 1108, the machine-learning model is evaluated. For example, an evaluation dataset can be obtained, for example, via user input or from a database. The evaluation dataset can include inputs correlated to desired outputs. The inputs can be provided to the machine-learning model and the outputs from the machine-learning model can be compared to the desired outputs. If the outputs from the machine-learning model closely correspond with the desired outputs, the machine-learning model may have a high degree of accuracy. For example, if 90% or more of the outputs from the machine-learning model are the same as the desired outputs in the evaluation dataset, the machine-learning model may have a high degree of accuracy. Otherwise, the machine-learning model may have a low degree of accuracy. The 90% number is an example only. A realistic and desirable accuracy percentage is dependent on the problem and the data.
In some examples, if the machine-learning model has an inadequate degree of accuracy for a particular task, the process can return to block 1106, where the machine-learning model can be further trained using additional training data or otherwise modified to improve accuracy. If the machine-learning model has an adequate degree of accuracy for the particular task, the process can continue to block 1110.
In block 1110, new data is received. In some examples, the new data is received from a remote database or a local database, constructed from various subsets of data, or input by a user. The new data may be unknown to the machine-learning model. For example, the machine-learning model may not have previously processed or analyzed the new data.
In block 1112, the trained machine-learning model is used to analyze the new data and provide a result. For example, the new data can be provided as input to the trained machine-learning model. The trained machine-learning model can analyze the new data and provide a result that includes a classification of the new data into a particular class, a clustering of the new data into a particular group, a prediction based on the new data, or any combination of these.
In block 1114, the result is post-processed. For example, the result can be added to, multiplied with, or otherwise combined with other data as part of a job. As another example, the result can be transformed from a first format, such as a time series format, into another format, such as a count series format. Any number and combination of operations can be performed on the result during post-processing.
A more specific example of a machine-learning model is the neural network 1200 shown in
The neurons and connections between the neurons can have numeric weights, which can be tuned during training. For example, training data can be provided to the input layer 1202 of the neural network 1200, and the neural network 1200 can use the training data to tune one or more numeric weights of the neural network 1200. In some examples, the neural network 1200 can be trained using backpropagation. Backpropagation can include determining a gradient of a particular numeric weight based on a difference between an actual output of the neural network 1200 and a desired output of the neural network 1200. Based on the gradient, one or more numeric weights of the neural network 1200 can be updated to reduce the difference, thereby increasing the accuracy of the neural network 1200. This process can be repeated multiple times to train the neural network 1200. For example, this process can be repeated hundreds or thousands of times to train the neural network 1200.
In some examples, the neural network 1200 is a feed-forward neural network. In a feed-forward neural network, every neuron only propagates an output value to a subsequent layer of the neural network 1200. For example, data may only move one direction (forward) from one neuron to the next neuron in a feed-forward neural network.
In other examples, the neural network 1200 is a recurrent neural network. A recurrent neural network can include one or more feedback loops, allowing data to propagate in both forward and backward through the neural network 1200. This can allow for information to persist within the recurrent neural network. For example, a recurrent neural network can determine an output based at least partially on information that the recurrent neural network has seen before, giving the recurrent neural network the ability to use previous input to inform the output.
In some examples, the neural network 1200 operates by receiving a vector of numbers from one layer; transforming the vector of numbers into a new vector of numbers using a matrix of numeric weights, a nonlinearity, or both; and providing the new vector of numbers to a subsequent layer of the neural network 1200. Each subsequent layer of the neural network 1200 can repeat this process until the neural network 1200 outputs a final result at the output layer 1206. For example, the neural network 1200 can receive a vector of numbers as an input at the input layer 1202. The neural network 1200 can multiply the vector of numbers by a matrix of numeric weights to determine a weighted vector. The matrix of numeric weights can be tuned during the training of the neural network 1200. The neural network 1200 can transform the weighted vector using a nonlinearity, such as a sigmoid tangent or the hyperbolic tangent. In some examples, the nonlinearity can include a rectified linear unit, which can be expressed using the following equation:
y=max(x, 0)
where y is the output and x is an input value from the weighted vector. The transformed output can be supplied to a subsequent layer, such as the hidden layer 1204, of the neural network 1200. The subsequent layer of the neural network 1200 can receive the transformed output, multiply the transformed output by a matrix of numeric weights and a nonlinearity, and provide the result to yet another layer of the neural network 1200. This process continues until the neural network 1200 outputs a final result at the output layer 1206.
Other examples of the present disclosure may include any number and combination of machine-learning models having any number and combination of characteristics. The machine-learning model(s) can be trained in a supervised, semi-supervised, or unsupervised manner, or any combination of these. The machine-learning model(s) can be implemented using a single computing device or multiple computing devices, such as the communications grid computing system 400 discussed above.
Implementing some examples of the present disclosure at least in part by using machine-learning models can reduce the total number of processing iterations, time, memory, electrical power, or any combination of these consumed by a computing device when analyzing data. For example, a neural network may more readily identify patterns in data than other approaches. This may enable the neural network to analyze the data using fewer processing cycles and less memory than other approaches, while obtaining a similar or greater level of accuracy.
Some machine-learning approaches may be more efficiently and speedily executed and processed with machine-learning specific processors (e.g., not a generic CPU). Such processors may also provide an energy savings when compared to generic CPUs. For example, some of these processors can include a graphical processing unit (GPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex programmable logic device (CPLD), a digital signal processor (DSP), a system on a chip (SOC), hardware accelerators (e.g., an artificial intelligence (AI) accelerator, cryptographic accelerator), a neural computing core, a neural computing engine, a neural processing unit, a purpose-built chip architecture for deep learning, and/or some other machine-learning specific processor that implements a machine learning approach or one or more neural networks using semiconductor (e.g., silicon (Si), gallium arsenide (GaAs)) devices. Furthermore, these processors may also be employed in heterogeneous computing architectures with a number of and a variety of different types of cores, engines, nodes, and/or layers to achieve various energy efficiencies, thermal processing mitigation, processing speed improvements, data communication speed improvements, and/or data efficiency targets and improvements throughout various parts of the system when compared to a homogeneous computing architecture that employs CPUs for general purpose computing. Still further, one or more of these processors may be used in applications that do not utilize machine learning.
According to embodiments discussed herein, the above-described computing devices and systems may be utilized to implement one or more components of an STS, such as a test manager, a test server, a network, a network sniffer, and/or a user interface. In many embodiments, this may facilitate reliable, accurate, and efficient testing of software. For example, the above-described computing devices and systems may be utilized to simulate a network for communication between SUT and a simulated test server. In several embodiments, the above-described computing devices and systems may facilitate one or more functionalities described herein including preventing an STS from advancing through a UI-workflow too quickly (e.g., test a result of an operation before the operation has completed) by identifying and/or waiting for predetermined network traffic to complete; preventing excessive delays to wait for necessary network requests to complete; and detecting changes to network traffic profiles driven from the Client (e.g., SUT, application server, test server, UIAT, STS). These and other features described herein may enable a computing device and/or system implementing one or more components of an STS to realize unique and advantageous functionalities, resulting in an improved computer.
Many embodiments are generally directed to techniques for improved automated software testing, such as by verifying operations are complete based on user interface and/or network traffic indications. Multiple embodiments may utilize a network sniffer to detect specific network traffic to verify completion of network requests and/or responses associated with an operation included in a workflow for performance by SUT 1304. The SUT 1304 may comprise one or more types of software applications and/or software components, such as a user interface application or an operating system (OS) application that utilizes a network interface with a test server). In many embodiments, the detection of specific network traffic may be used to accurately time operation durations and/or efficiently perform workflows to evaluate the SUT. In some embodiments, one or more portions of SUT 1304 may be implemented by the test server 1308. For example, the SUT 1304 may include an application hosted by the test server 1308 and/or an interface for interacting with the application, such as via network 1306. In some such examples, the interface for interacting with the application may be via a network access application (e.g., a web browser) implemented by a client.
In one or more embodiments, STS 1402 may utilize network sniffer 1414 to determine operations of a SUT 1404, such as those initiated by UIAT 1410, have completed. In many embodiments, the use of network sniffer 1414 with UIAT 1410 may be integrated into the workflow in real time (or near-real time), such as via test manager 1412. These and other features may allow the STS 1402 to precisely record timings and avoid adding fixed delays for the workflow to consistently function. For example, sniffing of network traffic in real time for specific network traffic associated with completion of an operation by the SUT can be used to determine when the operation is finished/completed regardless of whether there is an indication of the operation's completion provided/detected via user interface 1416. In many embodiments, accurate and real-time determination of completion times allows precise and reliable timing of operations and/or quick and consistent execution of a workflow to test software. It will be appreciated that although SUT 1404, STS 1402, and test server 1408 are illustrated as separate components, they may be included in one or more of the same and/or different components without departing from the scope of this disclosure. In some embodiments, each of the components may be implemented by a single machine, or a local group of machines. In such embodiments, testing can be simplified by not requiring/using multiple distinct machines to perform testing.
In various embodiments, SUT interface 1411 of UIAT may interact with the SUT 1404 via one or more interfaces, such as to initiate operations. In the illustrated embodiment, the SUT interface 1411 of UIAT 1410 interacts with the user interface 1416 to initiate an operation. Additionally, or alternatively, in some embodiments, the SUT interface 1411 may initiate an operation via an application programming interface (API). Once an operation has been initiated, the STS 1402 may detect an accurate end of the operation. For example, network sniffer 1414, integrated with the UIAT 1410 via test manager 1412, may look for specific network traffic. The test manager 1412 may wait for the UI to complete, accurately record that the operation is completed, and continue with the next step of the workflow. In many embodiments, the test manager 1412 may attempt to verify the response data. If incorrect data is detected, the workflow may be redirected to an error path and if the correct data is detected, the workflow may be continued. In various embodiments, an error path may include one or more operations performed in response to detection of an error and/or incorrect data. For example, an error path may include recording extra debug information regarding the issue, such as to help identify the cause of the issue. In some such examples, the extra debug information may include a video of the event. In addition, or alternative, to collecting more details about the error, the error path may be an alternative workflow due to the error being detected. For instance, the alternative workflow may include logging a user off and/or not adding an item to a shopping cart.
In several embodiments, network traffic may be recorded and/or monitored. For instance, network traffic, or characteristics thereof, may be stored in one or more computer-readable media (e.g., one or more of main memory, disk memory, flash memory, caches, registers, system memory, random access memory), such as by network sniffer 1414, UIAT 1410, test server 1408, and/or test manager 1412. In many such instances, the one or more computer-readable media may be collectively referred to as a test digest. In various embodiments, captured network traffic (e.g., traffic stored in the test digest) may be used to validate the accuracy of sent and received data in real-time. In one or more embodiments, the process of integrating sniffed network traffic with UI automation tools can significantly improve one or more of flow control, timing, and validation.
More generally, accurate timings (e.g., how long an operation takes to complete) may be important for software performance testing and engineering. Quick and consistent flow control can be crucial when automating software testing. In various embodiments, flow control may refer to the steps that the UIAT 1410 uses to perform the desired operations against the SUT 1404 (e.g., application under test). Several embodiments may additionally, or alternatively, verify and/or validate request and/or response data. For example, request data may be sent from SUT 1404 to test server 1408 and/or response data may be sent from test server 1408 to network interface 1418. In some embodiments, UIAT 1410 and/or SUT interface 1411 may be a UI automation tool for driving browsers or windows applications (e.g., C# based Ranorex®). Additionally, or alternatively, in various embodiments, network sniffer 1414 may comprise a browser-based network traffic sniffing tool with an API used to interface with network requests (e.g., HttpWatch® with a C# API). Accordingly, in various embodiments, UIAT 1410 and/or test manager 1412 may interact with network sniffer 1414 via an API.
In some embodiments, one or more components illustrated in
The SUT interface 1511 of UIAT 1510 may be used to interact with a client UI (e.g. a graphical user interface of the software under test) that sends requests to a test server (e.g., application server). In some embodiments, the SUT interface 1511 may interact with SUT via an API. The network sniffer 1514 may be used to determine when to progress through the test workflow 1520 (e.g., by identifying completion of an operation), based on criteria such as data transmission and data validation. In various embodiments, the criteria may be included in the test workflow 1520 and/or the test settings 1522. In many embodiments, the criteria may be customizable and/or includes one or more wildcard characters. More generally, the test workflow 1520 may include one or more operations associated with evaluation of a SUT by STS 1502 and the test settings 1522 may include one or more conditions and/or configurations for execution of the test workflow 1520 and/or controlling one or more operational aspects of the STS 1502. For example, test settings 1522 may indicate how often test manager 1512 should poll the network sniffer 1514. In another example, test settings 1522 may indicate how SUT interface 1511 should interact with the SUT (e.g., via a GUI or via an API).
Flow controller 1524 may be utilized to advance through the test workflow 1520 or redirect to an error path. For example, flow controller 1524 may advance to a next step of the test workflow 1520 or redirect from the test workflow 1520 to an error path based on network communications identified by network sniffer 1514 (e.g., traffic monitor 1535) and analyzed by response validator 1526. In many embodiments, response validator 1526 may interoperate with network sniffer 1514 (e.g., traffic monitor 1535) to perform live verification and error detection. In many such embodiments, the results of the live verification and error detection may be utilized by flow controller 1524 to determine whether to advance to a next step of the test workflow 1520 or redirect to an error path from the test workflow 1520. For example, test manager 1512 may utilize network sniffer 1514 to determine whether a network response includes the predetermined string “7305.0”. In such examples, if the string is not detected in the network response an error is detected and implementation of the test workflow 1520 is stopped and an error path is implemented. In another example, error detection may include detecting an HTTP status code for a client error or server error. In yet another example, error detection may include monitoring UI behavior for abnormalities, such as glitches, erroneous indications, and the like. In such other examples, the UI may be monitored to detect abnormalities in response to entering an error path based on network traffic detected (or not detected).
In one or more embodiments, test workflow 1520 may be adjusted to handle an error. In some embodiments, the workflow may be adjusted by skipping to the next method and not continuing down a path that is guaranteed to fail, which can reduce time and/or improve efficiency. For example, when an early step of creating a GUI chart fails, it is inefficient to continue creating that chart. Instead, a jump to trying the next chart may be performed (this failure may be detected by network traffic and not the UI, such as in instances that the chart is not supposed to render at all at this point). In various embodiments, the workflow may be adjusted by reattempting an operation that failed, which can save the rest of a run. The failed operation may still be logged, tracked, and/or marked as a failure. For example, when interacting with an ‘OK’ button (e.g., via clicking or selecting), the button may not be properly actuated, and the operation may not have taken place. Embodiments described herein may automatically retry interacting with the ‘OK’ button. In some such embodiments, failure to properly interact with the ‘OK’ button may be automatically determined based on network traffic (i.e., no user intervention required). In one or more embodiments, the workflow may be exited early, which may prevent the system from being left in a bad state (e.g., from continuing to perform steps) and/or save time by avoiding unnecessary execution of steps. In some embodiments, the unnecessary execution of steps in subsequent iterations to recover the system from a bad/unintended state may be avoided based on network traffic. For example, a failing run may be detected based on network traffic prior to the failing run leaving a system in an undesired state such as by adjusting settings based on old data that was not properly updated due to a failure to request or receive the updated data over a network.
The timer 1528 may be utilized to track and record timing for various operations performed as part of execution of the test workflow 1520. In some embodiments, the network sniffer 1514 may include the timer 1528 and/or an additional timer. These and other features may allow the STS 1502 to reliably function while precisely recording timings. For example, sniffing of network traffic in real time for specific network traffic associated with completion of an operation by the SUT can be used to determine when the operation is finished/completed regardless of whether there is an indication of the operation's completion provided/detected via a user interface. In many embodiments, accurate and real-time determination of completion times allows exact and reliable timing of operations and/or quick, unimpeded, and consistent execution of test workflow 1520.
In several embodiments, network traffic may be recorded/captured (e.g., via traffic recorder 1533 and/or monitored (e.g., via traffic monitor 1535). For instance, network traffic, and/or characteristics thereof, may be stored in one or more computer-readable media (e.g., one or more of main memory, disk memory, flash memory, caches, registers, system memory, random access memory), such as by traffic recorder 1533 and/or traffic monitor 1535. In some such instances, the network traffic, and/or characteristics thereof, may be stored in the test digest 1530. In some embodiments, the captured network traffic (e.g., traffic stored in the test digest 1530) may be used to validate the accuracy of sent and received data. In several embodiments, traffic recorder 1533 may listen and store network traffic while traffic monitor 1535 may analyze and/or take action on network traffic in real time. In other words, traffic recorder 1533 may listen and record, in real time, streaming network traffic and traffic monitor 1535 may interpret and/or act on, in real time, the network traffic and/or characteristics thereof (e.g., quantity and/or quality of traffic). For example, traffic recorder 1533 may store a history of network traffic in the test digest 1530 and traffic monitor 1535 may be used to identify specific network traffic (i.e., network completion data), in real time, to enable completion of an operation initiated by UIAT 1510 to be verified by response validator 1526. In another example, five HTTP requests that went to a uniform resource locator (URL), such as /reportData/jobs, may be listened for and/or five responses to the five requests that include the string “completed” may be listened for. In such other example, the absence of one or more of the requests and/or responses may result in error detection and/or initiating an error path.
In various embodiments, data collected and/or generated by one or more components of STS 1502 may be stored in one or more computer-readable media (e.g., one or more of main memory, disk memory, flash memory, caches, registers, system memory, random access memory) in one or more devices. In various such embodiments, the one or more computer-readable media, or data stored therein, may be collectively referred to as the test digest 1530. Accordingly, in several embodiments, test digest 1530 may comprise, or refer to, one or more portions of distinct and/or disparate data associated with implementation of test workflow 1520 by STS 1502.

In the illustrated embodiment shown in
In parallel with block 1706, at block 1708, the logic flow 1700 may wait to detect UI completion. For instance, UIAT may wait to detect an indication via UI 1416 (i.e., UI completion data) that the operation has completed. In the embodiment associated with code snippets 1800, 1900, 2000, 2100, a function, NotExists, is called in implementing block 1708. Continuing to block 1710, the timer may be stopped when both the specific network traffic and the UI completion are detected. For example, test manager 1512 may stop timer 1528 when test manager 1512 detects specific network traffic associated with completion of the UI operation and UIAT 1510 detects UI completion. In the embodiment associated with code snippets 1800, 1900, 2000, 2100, one or more inputs may be provided to a function, Stopwatch_Module ( ), in implementing block 1710 and block 1712.
At block 1712, the response/completion time may be recorded. For example, test manager 1512 may record the response time in test digest 1530. Proceeding to block 1714, the UI and network responses may be verified. For instance, response validator 1528 may verify one or more of the UI and network responses (i.e., one or more of the UI and network completion data). In various embodiments, network and/or UI completion data may be verified by comparison to predetermined network and/or UI completion data. For example, predetermined network and/or UI completion data may be stored in test settings 1522. In many embodiments, the predetermined network and/or UI completion data may include a range (e.g., 1-10) or variety (e.g., A, B, C, E, or 7) of values. In some embodiments, network completion data may comprise “state: completed” as part of a network response. In some such embodiments, the predetermined network completion data for the operation may be three network responses (e.g., one for each of the areas 1634) that include “state: completed”. Continuing to block 1716, UI and/or network data errors may be handled, if they occur. For example, test manager 1512 may redirect to an error path (e.g., by triggering an exception) in response to an error being detected in one or more of the UI and network responses by response validator 1528.
In the embodiment associated with code snippets 1800, 1900, 2000, 2100, one or more inputs may be provided to a function, CheckFileContents ( ), in implementing block 1714 and block 1716. Further, one or more portions of CheckFileContents ( ) is illustrated in code snippet 2100 of
In various embodiments, after block 1716, the logic flow 1700 may proceed to a next operation in the test workflow. If the next step of the test workflow involves initiation of another UI operation (i.e., operation initiated via a UI) that involves network traffic and recording the timing of the operation, the logic flow 1700 may return to block 1702. Similarly, if the next step of the test workflow involves initiation of an API operation (i.e., operation initiated via an API) that involves network traffic and recording the timing of the operation, the logic flow 1700 may proceed to block 1704 after initiation of the API operation. However, if the next step of the test workflow does not involve network traffic or is not timed, then logic flow 1700 may proceed to a different logic flow, and possibly return to logic flow 1700 later in the test workflow. In some embodiments, once the test workflow is complete, the network traffic may be analyzed. For example, network traffic captured by traffic recorder 1533 of network sniffer 1514 may be analyzed by test manager 1512.
In one or more embodiments, block 1706 and/or block 1708 may not be needed prior to block 1710 (see, e.g.,
In the illustrated embodiment shown in
At block 2208, after the logic flow 2200 has waited for the network request and/or response to complete, a network sniffer may be polled. For example, traffic monitor 1535 of network sniffer 1514 may be polled. Continuing to block 2210, it may be determined if the network request and/or response has completed based on polling of the network sniffer. If the network request and/or response has not completed, the logic flow 2200 may proceed to block 2212. At block 2212, it may be determined whether an error condition is satisfied. For example, test manager 1512 may determine whether an error condition has been satisfied based on test settings 1522. In another example, test manager 1512 may determine an error condition has been satisfied based on incorrect network completion data. If an error condition is not satisfied, the logic flow 2200 may return to block 2206. However, if an error condition is satisfied, the logic flow 2200 may proceed to block 2214. Referring back to block 2210, similarly, if the network request and/or response is determined to be completed at block 2210, the logic flow may proceed to block 2214. In many embodiments, error conditions may be checked, similar to block 2212, for when the network request and/or response is determined to be completed at block 2210 and prior to the logic flow may proceed to block 2214.
At block 2214 metrics regarding the initiated UI operation and/or implementation of the overall workflow may be verified/recorded/reported. For example, if the logic flow 2200 arrives at block 2214 from block 2210, metrics associated with completion of the network request and/or response may be recorded in a test digest. However, if the logic flow 2200 arrives at block 2214 from block 2212, metrics associated with the error condition and/or network request and/or response may be recorded in the test digest. Continuing to block 2216, it may be determined if the testing has completed and/or ended. For example, the testing may be ended after an error condition is satisfied or the testing may be completed after the test workflow has been performed. On the other hand, if no error condition has been satisfied (i.e., logic flow 2200 determines the network request and/or response has completed) and the test workflow has not been fully performed, the logic flow 2200 may return to block 2204 and the next UI operation in the workflow may be initiated. In other embodiments, the logic flow 2200 may proceed from block 2204 to block 2212, then to block 2214, block 2216, and return to block 2204 or end at block 2218. For example, operations that do not involve network communications may proceed in this alternate manner Additionally, or alternatively, logic flow 2200 may include one or more error paths that are followed/entered upon detection of an error.
In the illustrated embodiment shown in
Continuing to block 2306, operation of the user interface may be monitored to identify a response associated with performance of the first operation by the SUT. For example, operation of user interface 1416 may be monitored to identify a response associated with performance of the first operation by the SUT 1404. At block 2308 UI completion data may be determined based on the response identified from the user interface and associated with completion of the first operation by the SUT, wherein the UI completion data comprises an indication that the first operation has been performed by the SUT. For instance, removal of the loading bars from areas 1634 may be used to determine the UI completion data.
Proceeding to block 2310, network traffic associated with the first operation may be recorded in a test digest, wherein the test digest comprises one or more storage locations on one or more computer-readable media. For example, network traffic may be recorded in test digest 1530 by traffic recorder 1533. Continuing to block 2312, network traffic between the SUT and a test server may be monitored to detect specific network traffic associated with completion of the first operation by the SUT, wherein the specific network traffic associated with completion of the first operation by the SUT comprises one or more of a network request and a network response. For instance, network traffic between SUT 1404 and test server 1408 may be monitored by network sniffer 1414 to detect specific network traffic associated with completion of the first operation by the SUT.
At block 2314 network completion data may be determined based on detection of the specific network traffic associated with completion of the first operation by the SUT. For example, network complete data may be determined based on detection of HTTP call 1632-3. Proceeding to block 2316, the timer may be stopped in response to determination of the UI completion data and the network completion data. For instance, timer 1528 may be stopped in response to determination of the UI completion data and the network completion data. Continuing to block 2318, a response time may be recorded in the test digest for the first operation in the SUT based on an amount of time indicated by the timer. For example, a response time may be recorded in test digest 1530 based on an amount of time indicated by the timer 1528.
Proceeding to block 2320, the UI completion data may be verified based on comparison of the UI completion data to predetermined UI completion data. For instance, the UI completion data may be verified by response validator 1526 based on comparison of the UI completion data to predetermined UI completion data stored in test settings 1522. At block 2322 verification of the UI completion data may be recorded in the test digest. For example, verification of the UI completion data may be recorded in test digest 1530 by response validator 1526. Continuing to block 2324 the network completion data may be verified based on comparison of the network completion data to predetermined network completion data. For instance, the network completion data may be verified by response validator 1526 based on comparison of the network completion data to predetermined network completion data stored in test settings 1522.
At block 2326, verification of the network completion data may be recorded in the test digest. For example, verification of the network completion data may be recorded in test digest 1530 by response validator 1526. Proceeding to block 2328 a second operation may be initiated in the SUT with the UIAT based on verification of the UI completion data and the network completion data, wherein the second operation comprises one of the plurality of operations in the workflow for performance by the SUT during evaluation of the SUT, and wherein the UIAT initiates the second operation via the user interface of the SUT. For example, a second operation may be initiated in SUT 1404 with UIAT 1410 based on verification of the UI completion data and the network completion data.
