android - AmbiguousViewMatcherException意式浓缩咖啡

我正在尝试使用IdlingResource编写一个Espresso测试，以检查视频播放。

我的项目托管在here

这是测试：

@RunWith(AndroidJUnit4.class)
public class RecipeFetchTest {

@Rule
public ActivityTestRule<RecipeActivity> mActivityTestRule = new ActivityTestRule<>(RecipeActivity.class);

private IdlingResource mIdlingResource;

@Before
public void registerIdlingResource() {
    mIdlingResource = mActivityTestRule.getActivity().getIdlingResource();
    Espresso.registerIdlingResources(mIdlingResource);
}


@Test
public void checkRecipeNameRecipeActivity() {
    onView(ViewMatchers.withId(R.id.rv_recipes)).perform(RecyclerViewActions.scrollToPosition(1));
    onView(withText("Brownies")).check(matches(isDisplayed()));
}

@Test
public void checkPlayerViewIsVisibleRecipeDetailActivity1() {
    onView(ViewMatchers.withId(R.id.rv_recipes)).perform(RecyclerViewActions.actionOnItemAtPosition(0,click()));
    onView(ViewMatchers.withId(R.id.rv_steps)).perform(RecyclerViewActions.actionOnItemAtPosition(0,click()));
 withContentDescription("playerVideo"))).check(matches(isDisplayed()));
    onView(withId(R.id.playerView)).check(matches(isDisplayed()));
}


@After
public void unregisterIdlingResource() {
    if (mIdlingResource != null) {
        Espresso.unregisterIdlingResources(mIdlingResource);
    }
}

}

我得到测试失败，并显示以下错误：

android.support.test.espresso.AmbiguousViewMatcherException: '(with id:
gautamhans.xyz.bakeaid:id/playerView and is displayed on the screen to the
user)' matches multiple views in the hierarchy.
Problem views are marked with '****MATCHES****' below.

+--------->SimpleExoPlayerView{id=2131558584, res-name=playerView,
visibility=VISIBLE, width=871, height=399, has-focus=false, has-
focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true,
is-focused=false, is-focusable=false, is-layout-requested=false, is-
selected=false, root-is-layout-requested=false, has-input-connection=false,
x=0.0, y=0.0, child-count=3} ****MATCHES****

+---------->PlaybackControlView{id=2131558584, res-name=playerView,
visibility=VISIBLE, width=871, height=399, has-focus=false, has-
focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true,

selected=false, root-is-layout-requested=false, has-input-connection=false,
x=0.0, y=0.0, child-count=1} ****MATCHES****

根据测试，我有两个具有相同res-id的视图，即“ playerView”。

一种是SimpleExoPlayerView
另一个是PlaybackControlView

我记得定义了SimpleExoPlayerView，但没有定义PlaybackControlView。

因此，将不胜感激。

最佳答案

我有同样的问题。

我认为SimpleExoPlayer会自动生成一个PlaybackControlView。
我不知道我们是否可以避免这种情况，但是我得到了解决方法。

看这行：

onView(allOf(instanceOf(SimpleExoPlayerView.class), withId(R.id.playerView))).check(matches(isDisplayed()));

我只是添加一个Matcher以确保检查SimpleExoPlayer对象，然后检查它是否正确显示。
