You can run the junit4 test suite via:
./mach gradle test
(Note mcomella 5/5/16: they don't all pass for me locally)
This runs in automation as the "android-test" job.
These jobs run on [http://robolectric.org/ Robolectric], which mocks various Android libraries so you can write integration tests as unit tests. [http://mockito.org/ Mockito] is also supported for mocking (see [http://mxr.mozilla.org/mozilla-central/source/mobile/android/tests/background/junit4/src/org/mozilla/gecko/dlc/TestVerifyAction.java TestVerifyAction for a sample]).
You can also run specific tests from the IDE by selecting the "Build Variants" menu (bottom left), changing "Test Artifact" to "Unit Tests", right-clicking on the test class you want to run, and selecting the "Run <test-class>" option.
