For JUnit 3

For AWS Device farm you need to upload both apk, your app apk and your tests apk.

1. Run assemble task for AndroidTest.

# ./gradlew assembleDebugAndroidTest

NOTE: Debug is the buildType.

1. Check generated apks:
   • app.apk: app/build/output/apk/app-debug.apk.
   • test.apk: app/build/output/apk/app-debug-androidTest-unaligned.apk.

For JUnit 4 and Testing Support Library support

Oficial JUnit tags are not supported so you need to format names with:

1. Your test class should end with “Tests”.
2. Your tests method should start wiht “test”.

Example:

@RunWith(AndroidJUnit4.class)
@LargeTest
public class LoginActivityTests {

	@Rule
	public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule(LoginActivity.class);

	@Before
	public void setup() {
	}

	@Test
	public void testShowsRightDataOnCreate() {
		org.junit.Assert.assertEquals("asd", "asd");
	}
}
