尝试按照示例https://developer.android.com/guide/navigation/navigation-testing，我有一个预期的错误
org.mockito.exceptions.base.MockitoException：Mockito 无法模拟此类：类 androidx.navigation.NavController。
即使包含所有依赖项，如下所示： https: //developer.android.com/training/testing/set-up-project
@RunWith(AndroidJUnit4::class)
class MyShopFragmentTest {
@Test
fun testMyShopScenario_F001() {
// Create a mock NavController
val mockNavController = mock(NavController::class.java)
// Create a graphical FragmentScenario for the MyShopFragment
val myShopFragmentScenario = launchFragmentInContainer<MyShopFragment>()
// Set the NavController property on the fragment
myShopFragmentScenario.onFragment { fragment ->
Navigation.setViewNavController(fragment.requireView(), mockNavController)
}
// Verify that performing a click prompts the correct Navigation action
onView(ViewMatchers.withId(R.id.search)).perform(ViewActions.click())
verify(mockNavController).navigate(R.id.searchFragment)
}
}
任何想法？
趋势视图模型测试
@RunWith(JUnit4::class)
class TrendingViewModelTest {
private lateinit var trendingRepository: TrendingRepository
private lateinit var trendingViewModel: TrendingViewModel
@get:Rule
val schedulers = RxImmediateSchedulerRule()
@Before
fun setUp() {
trendingRepository = mock(TrendingRepository::class.java)
trendingViewModel = TrendingViewModel(trendingRepository)
}
@Test
fun testWithNetwork() {
trendingViewModel.isConnected = true
trendingViewModel.fetchTrendingRepos()
verify(trendingRepository, times(1)).getTrendingRepos()
}
//...
}
趋势视图模型
fun fetchTrendingRepos() {
if (isConnected) {
loadingProgress.value = true
compositeDisposable.add(
trendingRepository.getTrendingRepos().subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe({ response ->

RxImmediateSchedulerRule：
class RxImmediateSchedulerRule : …我打算用来FragmentScenario单独测试片段。在此片段中，我正在访问父活动以调用一些方法。为此，我正在使用CommonActivityOperations接口。我在此应用程序中使用导航架构组件。
interface CommonActivityOperations {
fun closeSearchBar()
fun navigateBackWithResult(resultFor: String, result: Bundle)
}
当我尝试在我的设备上运行测试时，AttractionDestinationFragment出现以下错误。
java.lang.ClassCastException: androidx.fragment.app.testing.FragmentScenario$EmptyFragmentActivity cannot be cast to .interfaces.CommonActivityOperations
