android - 尝试模拟 NavController 时出错

Question

尝试遵循示例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。

即使在包含所有依赖项之后：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？

对我来说，改变我的依赖

androidTestImplementation 'org.mockito:mockito-core:3.2.4'

至

androidTestImplementation 'org.mockito:mockito-android:3.2.4'

运作良好。
