androidx.test.espresso.NoMatchingViewException：层次结构中未找到匹配的视图
androidx.test.espresso.NoMatchingViewException: No views in hierarchy found matching
我正在尝试用 Espresso 测试我的片段。无论我尝试测试什么视图，我都会得到 NoMatchingViewException，我 100% 确定该视图确实存在于片段中。
这是我的测试：
@LargeTest
@ExperimentalCoroutinesApi
@RunWith(AndroidJUnit4::class)
class ExploreFragmentTest {
private lateinit var blogRepository: FakeBlogRepository
private lateinit var inAppMessagesRepository: FakeInAppMessageRepository
private lateinit var fakeFarRetailsRepository: FakeFarRetailsRepository
private lateinit var fakeUserProfileRepository: FakeUserProfileRepository
@Before
fun initRepository() {
blogRepository = FakeBlogRepository()
inAppMessagesRepository = FakeInAppMessageRepository()
fakeFarRetailsRepository = FakeFarRetailsRepository()
fakeUserProfileRepository = FakeUserProfileRepository()
ServiceLocator.blogRepository = blogRepository
ServiceLocator.inAppMessagesRepository = inAppMessagesRepository
ServiceLocator.userProfileRepository = fakeUserProfileRepository
}
@Test
fun noRetailsNearby_displaysNoRetailsNearbyLayout() = runBlockingTest {
// GIVEN - A fake repository with far retails
ServiceLocator.retailsRepository = fakeFarRetailsRepository
// WHEN - ExploreFragment launched to display retails
launchFragmentInContainer<ExploreFragment>(null, R.style.AppTheme)
// THEN - No retails layout is displayed on the screen
onView(withId(R.id.clExploreContainer)).check(matches(isDisplayed()))
}
}
这是相关片段的布局：

每次我 运行 测试都会得到这个错误：androidx.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: com.anagramma.myfoody.staging:id/clExploreContainer，不明白为什么。我是否遗漏了与浓缩咖啡框架相关的内容？
我的问题是我的片段在启动期间有一个 DialogFragment 覆盖了整个原始片段视图。由于 DialogFragment 有另一个生命周期，我的 Espresso 测试没有在父片段上找到任何视图 (ExploreFragment)。删除后 DialogFragment 视图匹配在我的测试中表现良好。
我正在尝试用 Espresso 测试我的片段。无论我尝试测试什么视图，我都会得到 NoMatchingViewException，我 100% 确定该视图确实存在于片段中。
