How to replace a @MockBean?

Question

Is it possible to replace an inherited @MockBean with the real @Bean?

I have an abstract class that defines many configurations and a setup for all ITests. Only for one single test I want to make use of the real bean, and not used the mocked one. But still inherit the rest of the configuration.

@Service
public class WrapperService {
       @Autowired
       private SomeService some;
}

@RunWith(SpringRunner.class)
@SpringBootTest(...)
public abstract class AbstractITest {
    //many more complex configurations

    @MockBean
    private SomeService service;
}

public class WrapperServiceITest extends AbstractITest {
    //usage of SomeService should not be mocked
    //when calling WrapperService

    //using spy did not work, as suggested in the comments
    @SpyBean
    private SomeService service;;
}

`this is invalid` because of the `SomeService` is an Abstract class or any other reason? — Mehraj Malik, Aug 06 '18 at 11:03
@MehrajMalik because `@MockBean` is a mock and thus cannot be autowired as real bean. — membersound, Aug 06 '18 at 11:06

Found a way using a test @Configuration conditional on a property, and overriding that property in the impl with @TestPropertySource:

public abstrac class AbstractITest {    
    @TestConfiguration //important, do not use @Configuration!
    @ConditionalOnProperty(value = "someservice.mock", matchIfMissing = true)
    public static class SomeServiceMockConfig {
        @MockBean
        private SomeService some;
    }
}


@TestPropertySource(properties = "someservice.mock=false")
public class WrapperServiceITest extends AbstractITest {
    //SomeService will not be mocked
}

Use @SpyBean to use the real bean.

I tried, but did not work. The bean is still mocked, see my edit. – membersound Aug 06 '18 at 11:10
`@Autowired` will inject the mock itself. – membersound Aug 06 '18 at 11:24
