Question

我已经完成了这些步骤

为避免赘肉，我们强烈建议您关闭用于测试的虚拟或物理设备上的系统动画。

在您的设备上，在“设置” - >“开发者”选项下，禁用以下3个设置：
  窗口动画刻度

  过渡动画刻度
  动画师持续时间表

但在我的代码中，我使用了这个

animation = new RotateAnimation(0f, 360f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
animation.setInterpolator(new LinearInterpolator());
animation.setRepeatCount(Animation.INFINITE);
animation.setDuration(5000);
imageScanLogo.startAnimation(animation);

在我的Espresso Test课程中，我使用

点击该视图

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

之后它会在那时停滞不前，不再前进了。当我从代码中评论动画时，它工作得很好。这是堆栈跟踪，它说他无法点击视图，但实际上他点击了它并且在测试中没有进一步的进展。

我的超时策略设置如下

@Before
    public void resetTimeout() {
        IdlingPolicies.setMasterPolicyTimeout(30, TimeUnit.SECONDS);
        IdlingPolicies.setIdlingResourceTimeout(20, TimeUnit.SECONDS);
    }

我不想评论代码中的每一个动画，也不想开始构建一些标志来启用/禁用测试的动画。

Answer 1

当应用程序处于空闲状态时，Espresso只对视图执行验证（所有AsyncTask都已完成）。默认情况下，它会等待60秒，然后抛出 AppNotIdleException ，您将此更改为30秒，在此期间您的应用尚未空闲，因此将其更改为更高的值可能有所帮助。

Answer 2

尝试使用Animator API，而不是the preferred animation method since Honeycomb (3.0)。

ObjectAnimator anim = ObjectAnimator.ofInt(imageScanLogo, "rotation", 0, 360);
anim.setRepeatCount(ValueAnimator.INFINITE);
animation.setInterpolator(new LinearInterpolator());
animation.setDuration(5000);
anim.start();

也许Espresso没有检查旧的动画API，或者在开发者设置中禁用动画并不适用于旧的动画。
