[FIXED] mockito Call real methods

Issue

I have this test: but the method checkIfHold is also mocked

@RunWith(MockitoJUnitRunner.class)
public class FrontSecurityServiceTest {

    @Mock
    private FrontSecurityService frontSecurityService
            = mock( FrontSecurityService.class, withSettings().defaultAnswer(CALLS_REAL_METHODS));

    @Test
    public void test1() {
        when(frontSecurityService.getLoggedInUserId()).thenReturn("000");
        frontSecurityService.checkIfHold(9L);
    }
}

I also tried with

   @Mock
    PerService perService;
    @Spy
    private FrontSecurityService frontSecurityService = new FrontOfficeSecurityService(perService);

but then is not mocking the method getLoggedInUserId(), getLoggedInUserId is public, non-static, and non-final.

I also tried, there it works, but MenService is called inside checkIfHold is null

@RunWith(SpringJUnit4ClassRunner.class)
public class FrontSecurityServiceTest {

    @Mock
    MenService menService;
    @Mock
    FrontSecurityService frontSecurityService;
    @Rule
    public MockitoRule rule = MockitoJUnit.rule();


    @Test
    public void test1() {

        MenReturn menReturn1 = MenReturn.builder().build();
        when(menService.getMen(anyString(), anyLong())).thenReturn(Arrays.asList(menReturn1));
         when(frontSecurityService.checkIfHold(anyLong())).thenCallRealMethod();
when(frontSecurityService.getLoggedInUserId()).thenReturn("000");
        frontSecurityService.checkIfHold(9L);
    }

}

Solution

I guess that @Spy is what you are looking for. Still, testing FrontSecurityService and also mock it at the same time seems odd to me. Try the following:

@RunWith(MockitoJUnitRunner.class)
public class FrontSecurityServiceTest {

    @Spy
    private FrontSecurityService frontSecurityService;

    @Test
    public void test1() {
        when(frontSecurityService.getLoggedInUserId()).thenReturn("000");
        frontSecurityService.checkIfHold(9L);
    }
}
