mongodb - junit中的模拟休息服务(带 Spring )

Question

我正在编写一个 junit 测试用例来测试其余调用。

我尝试模拟票务服务，它工作正常，但是当我在 REST 服务调用中模拟它时。它不会 mock 。

我正在使用带有 REST 的 springboot、mongodb。

有什么解决这个问题的建议吗？

@RestController
@RequestMapping("/ticket")
public class TicketRestController 
{
    @Autowired
    public TicketService ticketService;

    @RequestMapping (path = "/all", method = {RequestMethod.GET})
    public List<Ticket> getAllTicket() 
    {
        return ticketService.getAll();
    }
}


public interface TicketService
{

    public List<Ticket> getAll();
}


@Service
public class TicketServiceImpl implements TicketService {

  @Autowired
  TicketRepository ticketRepository;

  public List<Ticket> getAll() {
    return ticketRepository.findAll();
  }
} 



 public interface TicketRepository extends MongoRepository<Ticket, String>                            {

    public List<Ticket> findAll();

 }

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/mongo-repository-context.xml")
@WebAppConfiguration
public class TicketControllerTest extends AbstractTicketTest {

public static final String PATH = "/ticket";

public static final String ALL = PATH + "/all";

public static final String ID = PATH + "/id";

public static final String STATE = PATH + "/state";

public static final String PAYMENT_TYPE = PATH + "/paymentType";

public static final String TABLE_NUMBER = PATH + "/tableNumber";

@Autowired
private WebApplicationContext ctx;

private MockMvc mockMvc;

@Autowired
@InjectMocks
private TicketService ticketService;

@Mock
private TicketRepository ticketRepository;

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
    ticketRepository.deleteAll();
}

@Test
public void getAllTickets() throws Exception {
    Mockito.when(ticketRepository.findAll()).thenReturn(TicketMockProvider.createTickets());

    this.mockMvc.perform(get(ALL))
            .andExpect(status().isOk())
            .andExpect(jsonPath("$.*", hasSize(1)))
            .andExpect(jsonPath("$[0].ticketItems", hasSize(2)));
  }

Answer 1

问题是您的 TicketService 中使用的 TicketRepository 不是 mockito 模拟的那个。

您的测试类中的一个由 Mockito 本身实例化，而您的 TicketService 中的一个由 Spring 实例化。

您可以通过更改 init 方法使其工作:

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
    ticketRepository.deleteAll();
    // new code starts here
   ticketService.setTicketRepository(ticketRepository); // this method needs to be created.
}

这样，您的 TicketService 实例将使用模拟的 ticketRepository。
