Abstract: According to examples, an apparatus may include a processor that may schedule virtual users in a load test of a system under test. An apparatus may access user-specified or prestored points. Each point may represent a number of virtual users that is to place a load on the system under test at a given time. The apparatus may apply curve fitting, such as Bézier curve fitting, to generate a curve on a graph in which one axis represents time and another axis represents a number of virtual users at a given time. In some examples, the apparatus may use a smoothing factor to adjust the contours of the generated curve. The apparatus may use the curve to determine curve-fitted points to schedule virtual users at times corresponding to the curve-fitted points. To instantiate the virtual users, the system may use coroutines to reduce computational requirements for instantiating the virtual users.

Abstract: Features of each ordered step of a recorded test script for an application under test (AUT) are generated. The ordered steps are segmentally organized over actions based on feature relatedness of the ordered steps. Each action includes a contiguous subset of the ordered steps. The actions are hierarchically organized within a tree based on an ordered feature relatedness of the actions. The tree has nodes respectively corresponding to the actions. The actions are abstractedly related to one another based on an unordered feature relatedness of the actions to generate abstracted actions that each generalize a subset of the actions. Abstracted action groups are generated based on the abstracted actions and the tree. Each abstracted action group includes abstracted actions mapping to corresponding nodes of the tree within a same branch. The ordered steps of the recorded test script are collapsed into a series of instantiations of the abstracted action groups.

Abstract: Actions performed at a client application for a service during a session between the client application and the service. The client application runs on the client device and a service server hosts the service. Events received by a backend application running on a backend server from the service server during the session are also captured. The actions performed at the client application are correlated with the events received by the backend application from the service server. Backend application load testing data is generated. The backend application load testing data includes, for each action performed at the client application, the event received by the backend application from the service server that corresponds to the action.
