"Animators may only be run on Looper threads"在设备上入侵测试期间

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);
    }
}

按钮我点击使用espresso是基于材料主题，他们可能有一些动画下面。结果是，当我尝试运行一些工具测试时，每次我执行点击时应用程序都会崩溃。我试过在系统开发人员选项中关闭动画，但没有帮助。

这一行会导致我的应用程序崩溃:

btnFacebook.setEnabled(false);

编辑:我找到了合适的解决方案，寻找公认的答案。

Answer 1

好的，我找到了一个合适的解决方案!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，您正在存根的每个异步回调都应该使用Instrumentation的runOnMainSync(Runnable r)方法调用。例子:

    @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);
    }

Answer 2

尝试在模拟线程中调用该行:

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        btnFacebook.setEnabled(false);
    }
}, 100);
