测试无法执行点击并且没有记录意图

Question

我在创建测试时遇到两个问题：

1 - 当尝试测试触发我的活动按钮的 onClick 事件会打开一个新活动时，我看到该活动已在我的模拟器/设备中打开。但是，测试失败并给出无法执行 onclick 的跟踪。

我的代码：

@OnClick(R.id.my_activity_next_activity_button)
public void onNextActivityButtonClick(){
    Intent intent = new Intent(this, StreamingActivity.class);
    startActivity(intent);
}

测试：

@RunWith(AndroidJUnit4.class)
public class MyActivityTest{

   @Rule
    public IntentsTestRule<MyActivity> rule = new IntentsTestRule<>(MyActivity.class);

    @Test
    public void testButtonOnClickShouldOpenNewActivity(){

        onView(withId(R.id.my_activity_next_activity_button)).perform(click());
        Intents.intended(IntentMatchers.hasComponent(NewActivity.class.getName()));

    }
} 

我也尝试使用 InstrumentationTestCase，但结果相同：

   @Test
    public void testPickUpButtonShouldEmitPickUpIntentAndChangeStateToInitial(){

        Instrumentation.ActivityMonitor activityMonitor = new Instrumentation.ActivityMonitor(StreamingActivity.class.getName(), null, false);
        getInstrumentation().addMonitor(activityMonitor);

        onView(withId(R.id.activity_incoming_call_button_pick_up)).perform(click());

        Activity activity = activityMonitor.waitForActivityWithTimeout(5000);

        assertNotNull(activity);

    }

我得到的痕迹：

2 - 我发送的测试意图出现问题：

当我尝试测试我正在发送一个意图时（无论是启动一个活动还是通过 LocalBroadcast 发送一个），我找不到我的测试记录它的方式：

活动：

 @OnClick(R.id.my_activity_button_send_intent)
 public void onIntentButtonClick(){
    LocalBroadcastManager.getInstance(this).sendBroadcast(new Intent(Constants.INTENT_DEFAULT));
 }

测试：

    @Test
    public void testOnButtonClickShouldSendIntent(){
        onView(withId(R.id.my_activity_button_send_intent)).perform(click());
        Intents.intended(IntentMatchers.hasComponent(Constants.INTENT_DEFAULT));
    }

并跟踪：

android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: Wanted to match 1 intents. Actually matched 0 intents.

IntentMatcher: has component: has component with: class name: is "com.testproject.disframus:INTENT_DEFAULT" package name: an instance of java.lang.String short class name: an instance of java.lang.String

Matched intents:[]

Recorded intents:[]

你能指导我做错了什么吗？

Answer 1

出现第一个问题是因为 UI 线程上正在执行某些操作。例如。 StreamingActivity 在启动时确实在 ui 线程上工作（onCreate/onStart/onResume）或另一个 Activity（启动 Intent）阻塞 ui 线程，例如在onPause/onStop.

是否有任何活动

1. 在任何Activities 中显示不确定的ProgressBar（例如在onCreate()/onPause/onStop 中）？
2. 显示任何类型的动画或DrawableAnimation?
3. 在 ui 线程上工作？

到第二个问题。首先，意图匹配是错误的，hasComponent() 用于检查Intent 是否有正确的组件（例如Activity）要启动。您可以使用完整的限定名：

intended(hasComponent(StreamingActivity.class.getName());

不清楚，因为您没有发布所有代码，但如果 testOnButtonClickShouldSendIntent() 测试从问题一开始 StreamingActivity，那么 ui 阻塞问题也会阻塞录制意图。
