模拟对象在模拟对象下

Question

I need to mock the instance of a mocked object. I tried, but the object in coming as null.

Basically I need to try to call the real implementation as much as possible, the second level of mocking is not happening.

Any idea guys, how to do it.

public class mytest{

@Mock
Myutil myutil;

@InjectMock
ClassunderTest ct

  @Before
  setup()
  {
  MockitoAnotation.initMocks(ct);
  }

  @Test
  test1(){
    when(myutil.dotask()).thenReturn("");
    ct.m1();
  }
}

public class ClassunderTest{
@inject
MyUtil u1;
  public string m1(){
    u1.dotask();
  }
}

public class MyUtil(){
@inject
mockunderMock needtomock; //this instance needs to be mocked
  public dotask(){
      needtomock.play()
   }
}

A mock is not a real object so it doesn't have a needtomock field. You probably want to use a programmed behavior here ( Mockito.when() etc) or use a real MyUtil instance with a mocked mockundertest
