android - 在 Service 中发送广播并在 AndroidTestCase 中接收

Question

在我的项目中，当Service启动时，我发送一个广播:

Intent intent = new Intent("my.service.action");
intent.setPackage("com.my.project.test"); //only broadcast to my test project
getApplicationContext().sendBroadcast(intent);
Log.i("tag","broadcast is sent!");

在我的测试项目 AndroidTestCase 中，我启动并绑定(bind)了Service，这也触发了广播发送。所以，我决定也在我的 AndroidTestCase 中接收这个广播:

public class MyTestCase extends AndroidTestCase{ 
  ...
  @Override
  public void setUp() throws Exception{
    super.setUp();
     //This is working fine, I can see the broadcast is sent log in service
     bindToService() 

     //register broadcast receiver 
     IntentFilter filter = new IntentFilter("my.service.action");
     getContext().registerReceiver(mMyReceiver, filter);
  }

  public BroadcastReceiver mMyReceiver = new BroadcastReceiver(){

      @Override
      public void onReceive(Context context, Intent intent) {
      //BUT the broadcast sent in service is not received in my test case, why?
      Log.i(TAG, "Received in test case!");

     }  
 };
}

如您所见，我在测试项目的 AndroidTestCase 中注册了一个广播接收器。虽然广播是在我的项目的 Service 中发送的，但没有收到。为什么？

==========更新===========

在我删除此行后:intent.setPackage("com.my.project.test") 发送广播时，我在 AndroidTestCase 类中的接收器正在接收广播现在。

但是现在，我想知道为什么在test project 中显式设置package for intent 会阻止接收者，即使我设置的包名称是我的test project。在我的测试项目的 AndroidManifest.xml 中，我有我的包名定义:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.my.project.test"
   ...

@Override
  public void setUp() throws Exception{
    super.setUp();
     //This is working fine, I can see the broadcast is sent log in service
     bindToService() 

     //register broadcast receiver 
     IntentFilter filter = new IntentFilter("my.service.action");
     getContext().registerReceiver(mMyReceiver, filter);
  }

更改为:

@Override
  public void setUp() throws Exception{
    super.setUp();

     //register broadcast receiver 
     IntentFilter filter = new IntentFilter("my.service.action");
     getContext().registerReceiver(mMyReceiver, filter);

   //This is working fine, I can see the broadcast is sent log in service
     bindToService();

  }
