在设备入侵测试期间，“动画器只能在活套线程上运行”

Question

这是我的测试代码：

@RunWith(AndroidJUnit4.class)
@SmallTest
public class WelcomeActivityTests extends BaseTest {

    ApplicationController applicationController;

    @Rule
    public ActivityTestRule<WelcomeActivity> activityTestRule = new ActivityTestRule<>(WelcomeActivity.class);

    ArgumentCaptor<Callback> argumentCaptor;

    @Before
    @Override public void setUp() {
        applicationController = (ApplicationController) InstrumentationRegistry.getTargetContext().getApplicationContext();
        applicationController.setMockMode(true);
        argumentCaptor = ArgumentCaptor.forClass(Callback.class);
        super.setUp();
    }

    @Test
    public void testLogin() throws InterruptedException {

        onView(withId(R.id.btnLogInW)).perform(click());
        onView(withId(R.id.email)).perform(typeText("[e-mail]"));
        onView(withId(R.id.passL)).perform(typeText("strong.password"));
        onView(withId(R.id.btnLogInL)).perform(click());

        User user = new User();
        user.first_name = "Fake name";
        user.last_name = "Fake name";
        user.id = 1;
        user.email = "[e-mail]";

        AuthResponse authResponse = new AuthResponse();
        authResponse.api_key = "fake_api_key";
        authResponse.status = "ok";
        authResponse.user = user;

        Mockito.verify(api).login(Mockito.anyString(), Mockito.anyString(), Mockito.anyString(), argumentCaptor.capture());
        argumentCaptor.getValue().success(authResponse, null);

        assert true;
    }

    @After
    public void release() {
        applicationController.setMockMode(false);
    }

}

我用espresso点击的按钮是基于材料主题的，它们可能在下面有一些动画。结果是，当我试图运行一些入侵测试时，每次执行单击时应用程序都会崩溃。我试图在系统开发人员选项中关闭动画，但没有帮助。

这就是我的应用程序崩溃的台词：

btnFacebook.setEnabled(false);

编辑：我找到了合适的解决方案，寻找公认的答案。

好的，我找到了妥善的解决办法！当处理使用处理程序的库和API时，您需要用@UithReadTest注释您的测试用例。此外，应该使用runOnMainSync（Runnable r）检测方法调用您要进行stubbing的每个asynchronouos回调。示例：

    @Test
    @UiThreadTest
    public void testLoginSuccess() {

        Instrumentation.ActivityMonitor monitor = InstrumentationRegistry.getInstrumentation().addMonitor(EventsListActivity.class.getName(), null, true);

        onView(withId(R.id.btnLogInW)).perform(click());
        onView(withId(R.id.email)).perform(typeText("[e-mail]"));
        onView(withId(R.id.passL)).perform(typeText("strong.password"));
        onView(withId(R.id.btnLogInL)).perform(click());

        User user = new User();
        user.first_name = "Fake name";
        user.last_name = "Fake name";
        user.id = 1;
        user.email = "[e-mail]";

        final AuthResponse authResponse = new AuthResponse();
        authResponse.api_key = "fake_api_key";
        authResponse.status = "ok";
        authResponse.user = user;

        Mockito.verify(api).login(Mockito.anyString(), Mockito.anyString(), Mockito.anyString(), argumentCaptor.capture());
        InstrumentationRegistry.getInstrumentation().runOnMainSync(new Runnable() {
            @Override public void run() {
                argumentCaptor.getValue().success(authResponse, null);
            }
        });

        assertThat(1, equalTo(monitor.getHits()));
        InstrumentationRegistry.getInstrumentation().removeMonitor(monitor);
    }
