(The open source library Robotium was written to compensate for the lack of support for integration testing by ActivityinstrumentationTestCase2 (a class of the Android unit testing framework Instrumentation). ?Robotium not only provides more functions for operating controls on the basis of the dial API, but also realizes the functions that the dial does not support by calling the hidden functions of the system through reflection and other means. ?Robotium's relatively strong encapsulation of Instrumentation is the search of controls? Robotium supports Activity, Dialog, Toast, and Menu? Mainly used for automated integration testing)
