在單元測試期間在應用程序類中出錯

當我試圖通過robolectric執行我的應用程序類時，出現了奇怪的異常。我被困在幾個小時。有人可以幫我嗎？我的代碼片段如下：在單元測試期間在應用程序類中出錯

java.lang.RuntimeException: Stub!

我的代碼如下：

@RunWith(RobolectricGradleTestRunner.class) 
@Config(constants = BuildConfig.class,sdk = 18) 
public class MyApplicationTest extends ApplicationTestCase<MyApplication>{ 
    private MyApplication application; 

    public MyApplicationTest() 
    { 
     super(MyApplication.class); 
    } 
    @Before 
    public void setUp() throws Exception { 
     // super.setUp(); 
     createApplication(); 
     application = getApplication(); 

    } 

    @Test 
    public void testonCreate() throws Exception { 
    application.onCreate(); 
    }

請刪除'擴展ApplicationTestCase'。您已經從JVM運行它，而不是在設備上運行它。正確？ –

@EugenMartynov：是的，我從JVM運行它。我需要應用程序實例來處理我的測試用例，它將變爲空所以我搜索了createApplication（）將創建應用程序實例。如果我我將刪除ApplicationTestCase，那麼我將如何能夠獲得應用程序實例？ –

是的，你寫了謝謝！ –

不要用儀器測試混合JUnit測試：如果你需要的實例

@RunWith(RobolectricGradleTestRunner.class) 
@Config(constants = BuildConfig.class,sdk = 18) 
public class MyApplicationTest{ 
}

該應用程序然後使用RuntimeEnvironment.application。如果你想測試應用程序本身，然後創建它與new和調用它的方法，但它不應該Robolectric測試
