Test methods invocation with Mockito

I use Spring in my DAO and Service layer. Now i trying to test this layers with Mockito framework. What i want is just to check that appropriate method was called.

This is my configuration where i mocks all required dependencies:

@Configuration
public class MockConfig
{
    @Bean
    public EntityManagerFactory entityManagerFactory()
    {
        return mock(EntityManagerFactory.class);
    }

    @Bean
    public BaseRepositoryImpl baseRepositoryImpl()
    {
        return mock(BaseRepositoryImpl.class);
    }

    @Bean
    public BaseServiceImpl baseServiceImpl()
    {
        return mock(BaseServiceImpl.class);
    }
}

And this is how i trying to test this:

@ContextConfiguration(classes = MockConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class BaseServiceTest
{
    @Autowired
    private BaseService<Entity> service;

    @Autowired
    private BaseRepository<Entity> repository;

    @Test
    public void testSave()
    {
        Entity entity = new Entity("testId", "testName");
        service.save(entity);

        verify(service).save(entity);

        //try to test that Service calls appropriate method on Repository
        verify(repository).save(entity);
    }

But test fails on Repository mock. I want to ensure that Service calls appropriate method, and then its Repository(that is @Autowired in Service) calls appropriate method in turn. But seems that i misunderstood something about mocks. If anyone know how this can be accomplished please help. Thanks in advance.

You shouldn't be mocking your service in this case. Your service is the object under test; you need an actual instance of it.

@Configuration
@ComponentScan(basePackages = {"my.package.service"})
public class MockConfig {
    @Bean
    public BaseRepositoryImpl baseRepositoryImpl() {
        return mock(BaseRepositoryImpl.class);
    }
}

Then in your test:

@Autowired
@InjectMocks
private BaseService<Entity> service;

Finally, remove verify(service).save(entity);
