Question

我正在尝试测试应用程序的进度指示器，该视图在视图模型获取数据时会显示不确定的进度指示器。

为了测试这一点，我正在模拟提供者，该提供者返回数据并将其阻塞，直到我的测试给出告诉它继续进行为止。基本设置如下：

此代码很旧，因此提供程序正在使用@Test public void testProgressIndicator() { injectProvider(mockProvider); startTestActivity(); // The mock provider now runs on a worker thread and won't finish // until we tell it to. // We should now see a progress indicator. onView(withId(R.id.progress_indicator)).check( matches(withEffectiveVisibility(Visibility.VISIBLE))); // Tell the worker thread to finish up. mockProvider.setResult(); // The worker thread now returns a result, the progress indicator // should be gone. onView(withId(R.id.progress_indicator)).check( matches(withEffectiveVisibility(Visibility.GONE))); }在工作线程上使用阻塞代码。

但是，Espresso通常会等待所有工作人员完成，以确保结果不取决于时间。特别是，它使用AsyncTask等待所有未决的AsyncTaskPoolMonitor对象。通常情况下这很好，但就我而言，我想让该线程在Espresso继续运行时保持繁忙。如何告诉Espresso不要等待这个特定线程？

便宜的解决方案只是到AsyncTask并通过Thread或类似的方式进行通信，但是找到解决方案同时保留使用Handler的设置将是很好的选择。

当我进入调试器时，我发现我的测试运行程序线程卡在第一个AsyncTask上：

check()

Answer 1

您应该使用CountingIdlingResource，调用AsyncTask的onPreExecute（）中的crement（）和onPostExecute（）中的decrement（）

如何在Espresso中允许繁忙的工作线程
