java - Mocking a service in Spring 5.0.7.RELEASE

Question

I have a Spring 5.0.7.RELEASE app, with some WebLayer tests I have this test in my app:

@RunWith(SpringRunner.class)
@WebAppConfiguration
public class HongoControllerTest  {

    @Mock
    FactureService factureService;

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    ObjectMapper obj = new ObjectMapper();


    @Before
    public void setup() {

        MockitoAnnotations.initMocks(this);
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac)
                .build();

        when(factureService.setLockFilter(any())).thenReturn(Boolean.TRUE);
    }
}

but when I run the test, the FactureService is not mocked

Answer 1

I'm not totally sure because you didn't show an actual test but I guess you should use @MockBean and not @Mock.

@Mock is used for plain Unit Test when you do the dependency injection yourself. @MockBean is used for integration tests when you want to use your Mock as a regular Bean.

Long story shot. Try this:

@MockBean
FactureService factureService;
