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.
