Hilt + Espresso: No activities found. Did you forget to launch the activity by calling getActivity() or startActivitySync or similar?

When using Hilt with Espresso I found that my activity is either not resumed or not destroyed. When I comment out the very first test that launches my activity the second one started to pass. The workaround is to separate each test however this will produce a lot of boiler plate code.

Also I have a custom activity inside the tests that inherits from my main activity.

@RunWith(AndroidJUnit4.class)
@HiltAndroidTest
public class MainActivityTest {
    // ... initilisation & mocks


    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        hiltAndroidRule.inject();
        context = getInstrumentation().getTargetContext();
        
        // ... other initialisation and setup
    }

    // Helper classes and functions
    @AndroidEntryPoint
    public class ModifiedMainActivity extends MainActivity {
        // ... custom activity implementations
    }

    // Factory
    private SingleActivityFactory<MainActivity> activityFactory = new SingleActivityFactory<MainActivity>(MainActivity.class) {
        @Override
        protected MainActivity create(Intent intent) {
            ModifiedMainActivity mainActivity = new ModifiedMainActivity();
            // other custom activity configuration & setup
            return mainActivity;
        }
    }

    @After
    public void tearDown() {
        // ... other code to tear down some stubs
    }
}

Any ideas?

I can provide some code but other is under NDA.

My rules:

@Rule(order = 0)
public HiltAndroidRule hiltAndroidRule = new HiltAndroidRule(this);
@Rule(order = 1)
public ActivityTestRule<MainActivity> mainActivityRule = new ActivityTestRule<>(activityFactory, true, false);

Test example:

@Test
public void test_report_system_back_button_pressed_when_closing_main_activity() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    final MainActivity mainActivity = mainActivityRule.launchActivity(intent);
    getInstrumentation().runOnMainSync(mainActivity::onBackPressed);
    verify(mockedHelper, times(1)).reportEvent(eq(Codes.SYSTEM_BACK_PRESSED), eq("SystemBackPressed"), nullable(Map.class));
}

Exception:
