获取资源未发现异常使用robolectric

//Service class 
MyService extends Service { 

private SoundPool mSoundPool; 
private int mSoundID; 

@Override 
public void onCreate(){ 

mSoundPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); 
mSoundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() { 
    @Override 
    public void onLoadComplete(final SoundPool soundPool, final int sampleId, 
      final int status) { 
     mIsSoundLoaded = true; 
    } 
}); 
    //Here I am initializing soundpool and getting resource not found exception 
    // It should be context of CustomRobolectricTestRunner 
    mSoundID = mSoundPool.load(getApplicationContext(),R.raw.btn_click, 1); 

} 

}

//服务测试类获取资源未发现异常使用robolectric

@RunWith(CustomRobolectricTestRunner.class) 
//@RunWith(RobolectricTestRunner.class) 
public class MyServiceTest 
{ 

    @Test 
    public void testOnCreate() 
    { 
     // String hello = this.activity.getString(R.string.app_name); 
     // assertThat(hello, equalTo("Plus Box")); 

     MyService service = new MyService(); 
     service.onCreate(); // Getting exception Resource not found. 

     //To cross check, I have accessed resource in the following way 
     //and it working fine. I am able to access resource here. 
     /*  int resourceId = Robolectric 
       .getShadowApplication() 
       .getResources() 
       .getIdentifier("btn_click", "raw", 
         Robolectric.getShadowApplication().getPackageName()); 
     if (resourceId != 0) 
     { 
      // Raw folder contains resource. 
      System.out.println("The value of Raw ID " + resourceId); 
      assertTrue(true); 
     } 
     else 
     { 
      // Raw folder doesn't contain resource. 
      System.out.println("The value of Raw ID " + resourceId); 
      assertTrue(false); 
     } 
    */ 


    } 


}

即使我试图创建自己的自定义测试跑步，因为我的应用程序也有应用类（MyApplication的）。但似乎，它总是需要MyApplication上下文，而不是TestApplication。我跟着这个https://groups.google.com/forum/#!topic/robolectric/K2q8xAFfQOA链接。

public class TestApplication extends MyApplication { 

    @Override 
    public void onCreate() { 

     createSession(UserGroup.Unknown, 0, SessionState.Active, "", 0, ""); 


    } 

} 

public class CustomRobolectricTestRunner extends RobolectricTestRunner 
     implements TestLifecycle<Application> { 


    public CustomRobolectricTestRunner(final Class<?> testClass) 
      throws InitializationError { 
     super(testClass); 
    } 

    @Override 
    public void afterTest(Method arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void beforeTest(Method arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public Application createApplication(Method arg0, AndroidManifest manifest) { 

     TestApplication testApplication = new TestApplication(); 
     ShadowContextWrapper shadowApp = Robolectric.shadowOf(testApplication); 
     shadowApp.setPackageName("com.example.robolectric"); 
     testApplication.onCreate(); 

     return testApplication; 
    } 

    @Override 
    public void prepareTest(Object arg0) { 
     // TODO Auto-generated method stub 

    } 

}

任何帮助将非常appreicated。关注Yuvi

Robolectric 2.3引入了一个类似于ActivityController的ServiceController来帮助驱动服务的生命周期。

ServiceController<MyService> controller = Robolectric.buildService(MyService.class); 
MyService service = controller.attach().create().get()

或者干脆：

MyService myService = Robolectric.setupService(MyService.class);

此外，如果你想Robolectric使用你的测试应用程序类 - 那么，如果你的应用程序类被命名为“MyApplication的”，命名您的测试应用程序类的TestMyApplication“并将其放在您的测试目录下的相同包中。通过在类名前添加“Test”，它会告诉Robolectric使用TestMyApplication进行测试。（参考：http://robolectric.blogspot.ca/2013/04/the-test-lifecycle-in-20.html）

嗨，你错误地解释我的问题。我添加了更多的代码片段。我不会去测试或模拟来自Android框架的SoudPool相关类。我想做MyService类的单元测试。 – Yuvi
