尝试模拟 NavController 时出错

Question

尝试按照示例 https://developer.android.com/guide/navigation/navigation-testing，我遇到了预期错误

org.mockito.exceptions.base.MockitoException: Mockito 无法模拟此 class：class 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)
    }
}

有什么想法吗？

Answer 1

解决方案是使用 all-open 注释（https://kotlinlang.org/docs/reference/compiler-plugins.html) and configure the project as described here --> https://developer.android.com/training/testing/set-up-project

Answer 2

对我来说，改变我的依赖性

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

至

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

效果很好。
