java - 在单元测试期间在应用程序类中出错

Question

当我试图通过 robolectric 执行我的应用程序类时，我遇到了奇怪的异常。 我被困了几个小时。 有人可以帮我吗？我的代码 fragment 如下:

 java.lang.RuntimeException: Stub!

我的代码如下:

@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();
  }

不要将 JUnit 测试与仪器测试混合:

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

如果您需要应用程序的实例，请使用 RuntimeEnvironment.application。如果你想测试应用程序本身，那么只需使用 new 创建它并调用它的方法，但它不应该是 Robolectric 测试
