@EnableMockedBean
@SpringBootApplication
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes=MockedBeanTest.class)
public class MockedBeanTest {

    @MockedBean
    private HelloWorldService helloWorldService;

    @Autowired
    private MiddleComponent middleComponent;

    @Test
    public void helloWorldIsCalledOnlyOnce() {

        middleComponent.getHelloMessage();

        // THEN HelloWorldService is called only once
        verify(helloWorldService, times(1)).getHelloMessage();
    }

}

I have written a post explaining it.
