}

@Override
protected void tearDown() {
    if (mActivity != null)
        mActivity.finish();
}

 @Module(
 includes = MainModule.class,
 entryPoints = MainActivityTest.class,
 overrides = true
 )

static class TestModule {
    @Provides
    @Singleton
    Engine provideEngine() {
        return mock(Engine.class);
    }
}

@UiThreadTest
public void testLogoutButton() { …
