Question

我得到了以下测试用例：

Intent intent = new Intent("test");
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("test");
testReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
    recieved=true;
  }
};
getContext().registerReceiver(testReceiver,intentFilter );
pendingIntent.send();
Thread.sleep(100);

assertTrue(recieved);

有没有办法在没有Thread.sleep的情况下让这个测试通过？

您可以使用CountDownLatch等待类似的事情发生。你用计数初始化它。 await（）方法将等待计数达到0.当它执行时它们会停止阻塞（或者如果指定超时，如果它在计数达到0之前超时，则返回false）。

以下是修改为使用CountDownLatch的示例代码：

CountIntent intent = new Intent("test");
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("test");

final CountDownLatch countDownLatch = new CountDownLatch(1);
testReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
    countDownLatch.countDown();
  }
};
getContext().registerReceiver(testReceiver,intentFilter );
pendingIntent.send();

assertTrue(countDownLatch.await(1, TimeUnit.SECONDS));
