Question

我创建了一个简单的Spring WebFlux REST api，我想编写测试用例以端到端对其进行测试（不模拟）。

但是它会抛出错误消息。

这是我的课程。

其他控制器类

@RestController
@RequestMapping("/users")
public class UsersController {
    private final UserService userService;

    @Autowired
    public UserController(UserService userService) {
        this.userService = userService;
    }

    @RequestMapping(path = "list")
    public Mono<ResponseEntity> getusersList() {
        return userService.getusers();
    }

Rest Controller测试类


@RunWith(SpringRunner.class)
@WebFluxTest
public class UserControllerTestIT {
   @Mock
   private UserService userService;

   @Autowired
   private WebTestClient webTestClient;

   @Test
    public void testApplicationsList() {
        this.webTestClient
                .get()
                .uri("/users/list")
                .exchange();
    }
}

但是我收到以下错误消息。如何解决该问题？

如果您正在使用SpringRunner.class运行测试，则需要使用@MockBean而不是@Mock。

请参阅弹簧靴documentation

@RunWith(SpringRunner.class)
@WebFluxTest
public class UserControllerTestIT {
   @MockBean
   private UserService userService;

   @Autowired
   private WebTestClient webTestClient;

   @Test
    public void testApplicationsList() {
        this.webTestClient
                .get()
                .uri("/users/list")
                .exchange();
    }
}

此外，@WebFluxTest与@MockBean或@Import结合使用可以创建@Controller bean所需的任何协作者。
