如何測試的Android CursorLoader與robolectric

我想測試CursorLoader與robolectric 3.0-RC2如何測試的Android CursorLoader與robolectric

我的測試類：

@RunWith(RobolectricTestRunner.class) 
@Config(emulateSdk = 21) 
public class MyCursorLoaderTest { 

    @Before 
    public void setUp() { 
     final ContentProvider contentProvider = new MyProvider(); 
     contentProvider.onCreate(); 
     ShadowContentResolver.registerProvider(MyProvider.AUTHORITY, contentProvider); 
    } 

    @Test 
    public void testCursorLoader(){ 
     CursorLoader cLoader = new CursorLoader(RuntimeEnvironment.application, SomeColumns.CONTENT_URI, 
       SomeColumns.ALL_COLUMNS, null, null, null); 
     Cursor c = cLoader.loadInBackground(); 

     Robolectric.flushForegroundScheduler(); 

     assertNotNull(c.getCount()); 
    } 

    @Test 
    public void testContentResolver(){ 
     final Cursor c = RuntimeEnvironment.application.getContentResolver(). 
       query(SomeColumns.CONTENT_URI, 
         SomeColumns.ALL_COLUMNS, 
         null, null, null); 

     assertNotNull(c.getCount()); 
    } 
}

testContentResolver成功，但testCursorLoader失敗

堆棧跟蹤：

我在testCursorLoader有什麼變化？

它不應該是必要的創建和註冊您的內容提供商。它已經由Robolectric完成了。所以刪除你的setIp（）方法。而不是RobolectricTestRunner嘗試RobolectricGradleTestRunner。 – nenick

這是對我工作：

@Before 
public void setUp() { 
    final ContentProvider contentProvider = new MyProvider(); 
    ProviderInfo providerInfo = new ProviderInfo(); 
    providerInfo.authority = MyProvider.AUTHORITY; 
    contentProvider.attachInfo(RuntimeEnvironment.application, providerInfo); 
    contentProvider.onCreate(); 
    ShadowContentResolver.registerProvider(MyProvider.AUTHORITY, contentProvider); 
}
