We already executed our tests through the Android Studio. However, once you write them all, you will want to run them all at once. You can run all the unit tests for all build variants, but only for a certain flavor or build type. The same applies for instrumentation tests. We will show you several examples to do so using existing build variants for the Journaler application.
