Abstract: A machine may be configured to test an application based on an in-app impersonating of an audience profile. For example, the machine receives a selection of an audience identifier via a user interface. The machine maps the audience identifier to a configuration file that includes identifiers of features of the application available for use by the audience. The machine, based on the audience identifier and the configuration file, causes a display, in the user interface, of the identifiers of the features. The machine receives, via the user interface, a request to modify an operational state of a feature of the application in the software context associated with the audience. The machine configures, at run-time, the application based on the audience identifier, the configuration file, and the request to modify the operational state of the feature. The configuring results in the application including the feature in a modified operational state.

Abstract: In some embodiments, the disclosed subject matter involves a system and method relating to segmenting user population to test the quality of different software states. In at least one embodiment, the software states may be exposed dynamically to users who receive a software build, because features may be turned on/off via the server, at runtime. In an embodiment, if the server is unavailable, feature information may be retrieved from the local client storage. New features may be dynamically exposed to segments of a population to assist in verification and test of the new features. Other embodiments are described and claimed.
