@MockBean

Mocks will be automatically reset across tests.

Example

@RunWith(SpringRunner.class)
@SpringBootTest
public class SomeTest {

    @Autowired
    private TestRestTemplate restTemplate;

    @MockBean
    private SomeService someService;

    @Before
    public void setup() {

        // this stubs behavior
        given(someService.getSomething("blah")).willReturn(new Something("blah"));
    }

    @Test
    public void test() {

        restTemplate.getForEntity("/{username}/something, String.class, "blue");
    }
}
