Android fragments java.lang.IllegalStateException:在由launchFragmentInContainer引起的onSaveInstanceState之后无法执行此操作

我正在尝试测试应用程序工作流。导航组件已用于定义应用程序工作流。已使用FragmentScenario基于此引用（）测试从一个片段到另一个片段的导航

在build.gradle中添加了以下依赖项

debugImplementation（“androidx.fragment:fragment testing:1.1.0-beta01”）{
排除组：“androidx.test”，模块：“core”
}

用于访问api

launchFragmentInContainer

已使用Mock模拟导航控制器

下面是示例代码段

@RelaxedMockK
private lateinit var navController: NavController

@Before
fun setup() {
    MockKAnnotations.init(this)
}

@Test
fun navigationToSecondFragmentTest() {
    val secondFragmentScenario = launchFragmentInContainer<SecondFragment>()

    secondFragmentScenario.onFragment {
        Navigation.setViewNavController(it.requireView(), navController)
    }
    onView(ViewMatchers.withId(R.id.btn)).perform(ViewActions.click())
    verify{
        navController.navigate(R.id.secondFragment)
    }
}

确保正在运行测试的设备已解锁。如果屏幕关闭或处于锁定屏幕，您将获得大致如下所示的堆栈跟踪：

答案不正确，因为此测试未在物理设备上运行，所以活动和片段场景由构建环境计算机上的AndroidJUnit4测试运行程序运行。我希望这些场景将通过instrumentation runner和robolectric运行。在前一种情况下，锁定屏幕确实是一个合理且可能的原因
