Android unit-testing support
With IntelliJ IDEA X you can write unit tests for your Android application using Android Testing Framework.

Then, specify this tested module:
IntelliJ IDEA will automatically create a sample test class for your main activity (i.e. MyActivityTest). It’s handy that you can launch tests directly from editor. Note that it is important to choose an item with Android-specific icon for launching tests by Android Tests run configuration rather than using a default JUnit configuration:

Note, that scope of a dependency between Test module and Application module should be Provided.
