Android Kotlin：如果当前活动或应用程序已关闭，请进行集成测试

Question

我正在研究一个Android Kotlin项目。我正在使用Expresso测试框架为我的应用程序编写集成/ UI测试。我正在尝试为关闭我的应用程序或关闭当前打开的第一个/主要活动的场景编写测试。但它不起作用。

请参阅下面的测试代码。

@RunWith(AndroidJUnit4::class)
@LargeTest
class EventListTest: TestBuilder()
{
    @get:Rule
    val eventListActivityRule: ActivityTestRule<EventListActivity> = ActivityTestRule<EventListActivity>(EventListActivity::class.java, true, false)

    @Test
    fun itFinishesActivityWhenLogoutMenuItemIsTapped() {
        FakeEventService.SCENARIO_UNDER_TEST = 0
        this.eventListActivityRule.launchActivity(null)
        Intents.init()
        openActionBarOverflowOrOptionsMenu(ApplicationProvider.getApplicationContext<Context>())
        onView(withText(eventListActivityRule.activity.resources.getString(R.string.menu_item_logout))).perform(click())

        intended(not(hasComponent(EventListActivity::class.java.name)))
        Intents.release()
    }

}

[基本上，我正在测试单击注销菜单项时它将关闭当前活动。由于当前活动（EventListActiivty）是唯一打开的活动，因此它将完成该应用程序。在活动类中，它使用finish（）方法关闭自身。但是，当我运行测试时，出现以下错误。

我如何测试这种情况以及如何修复我的代码？

我也用过这个。

Assert.assertTrue(eventListActivityRule.activity.isDestroyed)

但是它也不起作用。

最后，我找到了解决方案。在这里。

Assert.assertTrue(eventListActivityRule.activity.isFinishing)

类似于测试操作栏后退按钮按下事件。
