java.lang.AssertionError: Status expected:<200> but was:<400> for Spring Boot Rest Controller Patch request

Question

Below is my controller (SalesOrderController.Java) and JUnit Test (SalesOrderControllerTest.Java)

@RestController

public class SalesOrderController extends BaseController {

/** The Constant LOGGER. */
private static final Logger LOGGER = LoggerFactory.getLogger(SalesOrderController.class);

/** The sales order service. */
@Autowired
private ISalesOrderService salesOrderService;

@CrossOrigin
@RequestMapping(value = "/issuers/{issuerId}/reassign-sales-orders", method = RequestMethod.PATCH, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
public BaseResponse reassignSalesOrder(@PathVariable("issuerId") final Long pIssuerId,
        @RequestBody @Valid final ReassignSalesOrderRequest pReassignSalesOrderRequest) {
    LOGGER.info("Reassigning sales orders of issuer:" + pIssuerId);
    return salesOrderService.reassignSalesOrder(pIssuerId, pReassignSalesOrderRequest);
}

}

and below is my Junit for above controller

@RunWith(MockitoJUnitRunner.class)

public class SalesOrderControllerTest extends AbstractBaseControllerTest {

/** The sales order service. */
@Mock
private ISalesOrderService salesOrderService;

/** The sales order controller. */
@InjectMocks
private SalesOrderController salesOrderController;

@Before
public void setUp() throws Exception {
    mockMvc = MockMvcBuilders.standaloneSetup(salesOrderController).build();
}

@Test
public void testReassignSalesOrder() throws Exception {
    ReassignSalesOrderRequest lSalesOrderUpdateRequest = new ReassignSalesOrderRequest();
    lSalesOrderUpdateRequest.setRedirectOption("Satellite");
    lSalesOrderUpdateRequest.setSatelliteId(200L);
    lSalesOrderUpdateRequest.setSalesOrderIds(Collections.singletonList(1L));
    when(salesOrderService.reassignSalesOrder(100L, lSalesOrderUpdateRequest)).thenReturn(new BaseResponse());
    ObjectMapper mapper = new ObjectMapper();
    mockMvc.perform(patch("/api/issuers/100/reassign-sales-orders")
            .contentType(MediaType.APPLICATION_JSON_UTF8).accept(MediaType.APPLICATION_JSON_UTF8)
            .content(mapper.writeValueAsString(lSalesOrderUpdateRequest)))
            .andExpect(status().isOk());
    verify(salesOrderService).reassignSalesOrder(100L, lSalesOrderUpdateRequest);
}

}

so why i am getting this error what's wrong in my code ?

Answer 1

I had the same issue. Be sure that your class ReassignSalesOrderRequest has all setters, getters and constructor ( mostly the no args constructor).

Answer 2

There are 2 easy ways to find out.

• Debug your test code and look at the response body and not just the status code. Or even assert on the body too.
• Set your log level to debug and surely your Spring application will also show the error for the incorrect client request.
