安卓Kotlin:集成测试当前活动或应用程序是否关闭

Question

我正在做一个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。我正试图为我的应用程序关闭或当前打开的第一个/主要活动关闭的场景编写一个测试。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，我正在测试它在单击注销菜单项时关闭当前活动。由于当前活动(EventListActiivty(是唯一打开的活动，它将完成应用程序。在活动类中，它使用finish((方法关闭自己。但是当我运行测试时，我得到了以下错误。

我如何测试这个场景，如何修复我的代码？

我也用过这个。

Assert.assertTrue(eventListActivityRule.activity.isDestroyed)

但它也不起作用。

最后，我找到了解决方案。给你。

Assert.assertTrue(eventListActivityRule.activity.isFinishing)

它类似于测试操作条后退按钮按下事件。
