Is there anyway to write unit test for my RestController without mocking the service using @MockBean?

@Autowired

private MockMvc mockMvc;



@MockBean

private CarService carService;





@Test

public void shouldReturnCarDetails() {



    //when(carService.getCarDetails(1)).thenReturn(new Car(1, 300));

    try {

        mockMvc.perform(MockMvcRequestBuilders.get("/api/cars/1")).andExpect(MockMvcResultMatchers.status().isOk())

                .andExpect(MockMvcResultMatchers.jsonPath("speed").value(300));

    } catch (Exception e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

    }

}`

There is another option called, @EnableWebMvc / mockMvc through which you can test your controller layer.

Code snippet given below,

*
* The TransactionsControllerTest class implements Junit functionality that
* simply connect to the controller layer (TransactionsController) and test the
* controller layer with some pre-defined/test value. This class also provides
* the details result for each test cases.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { TransactionsController.class, AppConfig.class, AppInitializer.class })
@EnableWebMvc
public class TransactionsControllerTest {
private static final Logger logger = Logger.getLogger(TransactionsControllerTest.class.getName());
private MockMvc mockMvc = null;
String values = null;

@InjectMocks

private WebApplicationContext wac;



/**

 * This Junit test method assigns required resources value before use.

 */

@Before

public void setup() throws Exception {

    values = TransactionConstant.AUTHORIZATION_CODE;

    mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();

}



/**

 * This Junit test method is used to test controller layer api,

 * "/transactions/getAllTransactionList"

 */

@Test

public void getAllTransactionList_Test() {

    try {

        logger.info("Logger Name: getAllTransactionList_Test() :: " + logger.getName());

        ObjectMapper mapper = new ObjectMapper();

        MvcResult result = mockMvc.perform(get("/getAllTransactionList").header("authorization_code", values))

                .andReturn();

        JsonNode root = mapper.readTree(result.getResponse().getContentAsString());

        JsonNode resultNodes = root.path("result");

        logger.debug("Junit Response :: resultNodes :: getAllTransactionList_Test() :: " + resultNodes.asText());

        assertEquals(resultNodes.asText(), "success");

    } catch (Exception e) {

        logger.error("Junit :: Exception :: getAllTransactionList_Test() ::  ", e);

    }
