首先,我是Java堆栈的新手,为了防御起见,我可能会问一些愚蠢的事情,谢谢您的耐心等待!
我需要的:
集成测试,但不发出外部请求。这意味着我必须在堆栈中比普通单元测试更深的地方模拟依赖项。
我也不想在上下文中加载所有堆栈。
预期:
只能使用@BeanMock模拟客户端并通过测试。 (根据我的试验,这只会嘲笑第一级深度)。
实际:
使用当前设置,我得到Error creating bean with name 'com.example.demo.SomeControllerTest': Unsatisfied dependency expressed through field 'webClient'
如果我使用@WebFluxTest(SomeController.class)
和ContextConfiguration(...)
,则客户端最终将为null。如果再添加@TestConfiguration
,则webflux抱怨例如在@Configuration
冲突中存在一些注释。
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");
}
}
最佳答案
@RunWith(SpringRunner.class)
@WebFluxTest(SomeController.class)
@ContextConfiguration(classes = {
SomeController.class,
SomeService.class
})
public class SomeControllerTest {
@Autowired
private WebTestClient webClient;
// ...
}
这是必需的组合,但是我不明白为什么要在活动上下文中添加
SomeController.class
的原因,@WebFluxTest
也不能这样做吗?要么
@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");
}
}
