Spring Framework - Mock is not mocking

Question

I have a Spring MvC app. (The Spring Framework is an application framework and inversion of control container for the Java platform) with this test:

    @RunWith(SpringJUnit4ClassRunner.class)
    public class AutorisationServiceTest {
    
        @Autowired
        @InjectMocks
        private IAutorisationService service;
    
        @Mock
        PersonneRepository personneRepository = Mockito.mock(PersonneRepository.class);
    
    
        @Before
        public void setup() {
        }
    
    
        @Test
        public void should_Find_GardeWith2Affectations() throws IOException {
    
            when(personneRepository.getAll(anyString())).thenReturn(DataLoader.mockData());
            service.getAll("rules");
        }
    
    }

    @Service
    public class AutorisationService implements IAutorisationService {
    
        private final PersonneRepository personneRepository;
    
        public AutorisationService(PersonneRepository personneRepository) {
            this.personneRepository = personneRepository;
        }

@Override
    public List<User> getAll(String where) {
        return personneRepository.getAll(where));
    }
    ...
    }

but when I run the test it seems no to mock the repo

You should decide whether you want to write a Spring test or a Mockito test.

A spring test will load the full context and you can then work with @Autowired and @MockBean:

@RunWith(SpringJUnit4ClassRunner.class)
public class AutorisationServiceTest {
    
  @Autowired
  private IAutorisationService service;
    
  @MockBean
  PersonneRepository personneRepository;

A Mockito test runs much faster, but you will only have the objects you explicitly configured with @InjectMocks or @Mock:

@RunWith(MockitoJUnitRunner.class)
public class AutorisationServiceTest {
  
  @InjectMocks
  private IAutorisationService service;
    
  @Mock
  PersonneRepository personneRepository;

Note that you never have to instanciate the mock with Mockito.mock() when using annotations and specialized runners.

I guess your PersonneRepository is a @Service, @Component or @Repository. So you should use auto-wiring here as well:

@Service
public class AutorisationService implements IAutorisationService {

   @Autowired    
   private PersonneRepository personneRepository;
