Abstract: Mobile devices executing applications may be tested for networking issues by utilizing a test network having proxy access devices placed at different physical locations. Devices may be stored in a secure enclosure that includes a host device. The enclosure includes access controls to prevent unauthorized removal of devices or access to stored data. If an unauthorized access, disconnection from the host device, or disconnection of a device from a power source is detected, devices may be placed into a locked state or data on the devices may be deleted. The enclosure may also include a control device for testing the exchange of Bluetooth data by the devices. The enclosure may also include conductive members placed on the touch sensors of devices for providing simulated touch input to the touch sensors by changing the capacitance of adjacent regions of the touch sensors.

Abstract: Mobile devices executing applications utilize data services worldwide, with issues involving the transfer of data on the network impacting the operation and user experience of those applications. Network data is acquired from a mobile computing device during communication and processed to determine occurrence of a burst which is representative of elements in the network data that are determined to be causally related. Bursts are analyzed, and those associated with poor performance are presented in a user interface. The user interface provides impact information about the effect the burst had on operation of the application. The user interface may provide suggestions to mitigate the poor performance. If no problem is determined by the system, but the user believes a problem to have occurred, user input is collected and used to trigger a workflow to analyze the burst. Subsequent results of this analysis are returned to the user via the user interface.

Abstract: Mobile devices worldwide execute applications that utilize data services, with issues involving the transfer of data via networks impacting the operation and user experience of those applications. Data is acquired from a mobile computing device executing an application and processed to determine occurrence of a group of related activities performed when executing the application. Parameters of the activities are analyzed, and those parameters associated with poor performance are presented in a user interface. The interface provides impact information about the effect of the activities on operation of the application and may include recommended actions to mitigate the poor performance. A user may interact with data within the interface to trigger a workflow to analyze indicated portions of the data. Subsequent results of this analysis may be returned to the user via the user interface or may be implemented as analytic rules for subsequent data processing.

Abstract: A test device may include a performance module to determine entropy values for images, such as of a graphical user interface, to be presented on a display device of the test device. An entropy value for an image may be indicative of a distribution of data values, such as intensity or color values for pixels in the image. Patterns of entropy values over time may provide information indicative of performance of the test device. For example, a constant entropy value over time may indicate the graphical user interface is not changing. In another example, particular patterns of entry values over time may be indicative of presentation of wait indicators or other user interface elements. The entropy values may be used to determine data indicative of performance of the test device. This data may be stored locally, sent to an external device, and so forth.

Abstract: Mobile devices executing applications utilize data services worldwide. Testing of the applications for networking issues is facilitated by utilizing a test network having proxy devices placed at different physical locations. A tester may use the test network to direct traffic to and from an application under test to one of the proxy devices. Using the proxy device, the traffic is then exchanged with a real-world network, such as a cellular data network, at the different locations. The tester may thus test operation of the application under test in real-world conditions at a variety of different physical locations. The system may include a proxy host device with an intermediate module to establish Virtual Private Network (VPN) connections and to capture VPN data, including VPN protocol data, session data, and other data. The VPN data may be provided to a network system to analyze performance of an application under test.

Abstract: A mobile device executes an application and is remotely controlled by a client device. To reduce bandwidth used during operation, a rate limiter selects a portion of data from the mobile device to be sent to the client device. A timer value is specified. The rate limiter on the mobile device, on an ongoing basis, updates a pointer to the latest data stored in memory, such as a latest frame of an image presented by a display of the mobile device. When the elapsed time since last data sent is greater than or equal to the timer value, the latest data is sent to the client device, and the timer is reset.

Abstract: Mobile devices executing applications utilize data services worldwide. The application executing on these mobile devices may be tested using proxy access devices (PADs) located at various points-of-presence (POPs) at different geolocations. A plurality of PADs in a high density configuration are managed to provide a pool of accessible devices at a POP for developers to utilize in testing. The PADs may comprise consumer-grade devices which individually are less reliable than that desired by an operator of the POP. Systems are used to provide a desired level of reliability by maintaining a reserve of additional PADs, automatically fixing problems, generating trouble tickets for more detailed troubleshooting, and so forth.

Abstract: Described herein is a system generating and sending shortcuts from a sending device to a receiving device. In one implementation, the sending device generates shortcut reference data (SRD) which includes application data indicative of a state of an application and a hash based on the application data. The SRD is sent to a shortcut server, while shortcut delivered data (SDD) which includes the hash value is sent to a recipient device. The recipient device may use the hash value of the SDD to request and receive the application data from the shortcut server. Once received, an application installed on the recipient device recreates on the recipient device the state of the application as originally presented on the sending device. As a result, a user at the sending device may share their experience with a user at the receiving device. Fees associated with the use of the system may be calculated.

Abstract: Application validation is performed based on object level hierarchy data associated with the application. An application is executed on a physical or emulated host device, and assembly code is generated for the executing application. The assembly code is analyzed to identify objects associated with the application, and to identify relationships between the objects. Based on the object and relationship data, an object level hierarchy is generated for the application. Validation of the application may be performed by comparing an object level hierarchy for a current version of the application to a previously generated hierarchy for a previous version of the application to identify differences between the two hierarchies.
