Multiple levels of @Mock and @InjectMocks

Question

So I understand that in Mockito @InjectMocks will inject anything that it can with the annotation of @Mock, but how to handle this scenario?

@Mock
private MockOb         


        

Answer 1

It is possible by combining @Spy with @InjectMocks. For your example, it would be:

@Spy
private MockObject1 mockObject1 = new MockObject1 ();

@Spy @InjectMocks //if MockObject2 has a MockObject1, then it will be injected here.
private MockObject2 mockObject2 = new MockObject2 ();

@InjectMocks
private SystemUnderTest systemUnderTest;
