WebTestClient 未注入

Question

首先，我是 java 堆栈的新手，在我看来，我可能会问一些愚蠢的问题，谢谢您的耐心！

我需要的：

集成测试，但没有发出外部请求。这意味着我必须在堆栈中比正常单元测试更深的地方模拟依赖项。我也不想加载上下文中的所有堆栈。

预期的：

能够使用 @BeanMock 仅模拟客户端并让测试通过。（根据我的试验，这只是深度模拟了第一级）。

实际的：

根据当前的设置，我得到了

Error creating bean with name 'com.example.demo.SomeControllerTest': Unsatisfied dependency expressed through field 'webClient'

如果我使用@WebFluxTest(SomeController.class)并且ContextConfiguration(...)客户端最终为空。例如，如果我添加@TestConfigurationwebflux 就会抱怨某些注释存在冲突。@Configuration

任何想法都将不胜感激！

@RestController
public class SomeController {
  private final SomeService someService;

  @Autowired
  public SomeController(SomeService someService) {
    this.someService = someService;
  }


  @GetMapping(value = "/endpoint")
  public Mono<String> endpoint() {
    return someService.get();
  }
}


@Service
public class SomeService {
  private final Client client;

  @Autowired
  public SomeService(Client client) {
    this.client = client;
  }

  public Mono<String> get() {
    return client.build().get().retrieve().bodyToMono(String.class);
  }
}


@Component
public class Client {
  private final HttpServletRequest request;

  @Autowired
  public Client(HttpServletRequest request) {
    this.request = request;
  }

  public WebClient build() {
    return WebClient.builder()
      .baseUrl("https://httpstat.us/200")
      .build();
  }
}

@RunWith(SpringRunner.class)
@TestConfiguration
@SpringBootTest(classes = {
  SomeController.class,
  SomeService.class
})
@AutoConfigureWebTestClient
public class SomeControllerTest {
  @Autowired
  private WebTestClient webClient;

  @MockBean
  private Client client;


  @Before
  public void setUp() {
    when(client.build())
      .thenReturn(WebClient.create("https://httpstat.us/201"));
  }

  @Test
  public void deepMocking() {
    webClient.get()
      .uri("/endpoint")
      .exchange()
      .expectStatus().isOk()
      .expectBody(String.class).isEqualTo("201 Created");
  }
}

Answer 1

@RunWith(SpringRunner.class)
@WebFluxTest(SomeController.class)
@ContextConfiguration(classes = {
   SomeController.class,
   SomeService.class
 })
 public class SomeControllerTest {
   @Autowired
   private WebTestClient webClient;
   // ...
 }

这是所需的组合，但我不明白为什么需要添加SomeController.class到活动上下文中，难道不@WebFluxTest这样做吗？

或者

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {
  SomeController.class,
  SomeService.class,
})
// @AutoConfigureWebTestClient // does absolutely nothing?
public class SomeControllerTest {
  @Autowired
  private SomeController controller;

  // ...

  @Test
  public void deepMocking() {
    WebTestClient.bindToController(controller)
      .build()
      .get()
      .uri("/endpoint")
      .exchange()
      .expectStatus().isOk()
      .expectBody(String.class).isEqualTo("201 Created");
  }
}
