Question

我有一系列测试幻灯片菜单的Espresso测试。打开“使用主机GPU”时，大多数测试失败，但禁用时则不会失败。即使我已禁用动画，我想我可能会在某个地方错过设置，因为我仍然可以看到窗口滑动打开。我正在测试Android 4.4.2并使用HAXM。为什么这个测试失败了？

这是测试的一个例子（它们都具有相同的结构）：

@SuppressWarnings("unchecked")
public void testClickOnItemDisplaysMyFragment() {
    openDrawer(DRAWER);
    onView(withId(DRAWER)).check(matches(isOpen()));
    onView(allOf(withId(DRAWER_ITEM), withText(MY_ITEM))).perform(click());
    onView(withId(DRAWER)).check(matches(isClosed()));

    Fragment fragment = fragmentManager.findFragmentById(FRAGMENT_LAYOUT);
    assertThat(fragment, is(notNullValue()));
    assertThat(fragment, is(instanceOf(MyFragment.class)));
    onView(withId(fragment.getId())).check(matches(isDisplayed()));
}

如果我在没有选中使用主机GPU的情况下启动我的模拟器，则测试通过正常。如果启用了“使用主机GPU”，则第一次测试通过，然后其余测试通过：

我已尝试在模拟器中禁用动画，如下所述：https://code.google.com/p/android-test-kit/wiki/Espresso#Getting_Started，但我仍然可以看到抽屉滑动打开和关闭。

这是一个已知错误：https://code.google.com/p/android-test-kit/issues/detail?id=64

启用“使用主机GPU”时，Espresso测试会冻结
