유휴 리소스가 안드로이드의 두 번째 활동에서 작동하지 않습니다

두 개의 Activities A and B 가 있습니다 . 500ms 동안 백그라운드 스레드를 실행하고 TextView 를 업데이트합니다. . 한 번 TextView   TextView 를 클릭하면 업데이트됩니다   B Activity 에 가다 . Activity B 에서  500ms 동안 실행중인 다른 백그라운드 스레드가 있고 TextView 를 업데이트합니다.   B Activity 에서 . Espresso 를 사용 하여이 흐름을 테스트하고 있습니다. . 나는 background thread 를 기다립니다   Idling Resource 를 사용하여 실행을 완료하려면 . Idling Resource 사용에 문제가 있습니다   B Activity . 코드를 아래에 내려 놓았습니다.

MainActivityTest.java:

@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityTest {
    @Rule
    public ActivityTestRule<MainActivity> mainActivityActivityTestRule = new ActivityTestRule<>(MainActivity.class);
    private IdlingResource mIdlingResource;
    @Before
    public void registerIdlingResource(){
        mIdlingResource = mainActivityActivityTestRule.getActivity().getIdlingResource();
        // To prove that the test fails, omit this call:
//        Espresso.registerIdlingResources(mIdlingResource);
        IdlingRegistry.getInstance().register(mIdlingResource);
    }
    @Test
    public void mainScreenLoads(){
        onView(withId(R.id.my_text)).check(matches(ViewMatchers.withText("Boom")));
        onView(withId(R.id.my_text)).perform(click());
        onView(withId(R.id.second_text)).check(matches(ViewMatchers.withText("Boom")));
    }
    @After
    public void unregisterIdlingResource() {
        if (mIdlingResource != null) {
//            Espresso.unregisterIdlingResources(mIdlingResource);
            IdlingRegistry.getInstance().unregister(mIdlingResource);
        }
    }
