如何解决Spring webflux 测试
我有一个带有以下服务的 Spring webflux 应用程序。
@Configuration
public class RouterConfiguration {
@Autowired
private RegistrationHandler regHandler;
@Bean
public RouterFunction<ServerResponse> regRoute() {
return RouterFunctions.route(POST(REGISTER_PATH).and(accept(APPLICATION_JSON)),regHandler::register);
}
}
public Mono<ServerResponse> register(ServerRequest request) {
return request.bodyToMono(Register.class).flatMap(reg -> {
return buildOrg(reg).flatMap(orgRepository::save).flatMap(org ->
ServerResponse.created(URI.create(USER_RESOURCE_URI + p.getUserId())).build());
});
}
我想测试上面的 API 和我的测试示例，
@ExtendWith({ SpringExtension.class,RestDocumentationExtension.class })
@WebFluxTest({ RegistrationHandler.class })
@AutoConfigureWebTestClient(timeout = "100000")
class RegistrationHandlerTest {
@Autowired
ApplicationContext context;
@MockBean
PasswordEncoder passwordEncoder;
@MockBean
private OrgRepository orgRepository;
@MockBean
private UserRepository usrRepository;
@Captor
private ArgumentCaptor<Organization> orgInputCaptor;
@Captor
private ArgumentCaptor<Mono<Organization>> orgMonoInputCaptor;
@Captor
private ArgumentCaptor<User> usrInputCaptor;
private WebTestClient webTestClient;
@BeforeEach
void setUp(RestDocumentationContextProvider restDocumentation) {
webTestClient = WebTestClient.bindToApplicationContext(context).configureClient()
.filter(documentationConfiguration(restDocumentation)).responseTimeout(Duration.ofMillis(100000))
.build();
}
@Test
@WithMockUser(username = "admin",roles = { "USER","ADMIN" })
public void testRegister() {
final Register register = new Register();
register.setorgName("testOrg");
register.setUsername("testUser");
register.setPassword("testPwd");
register.setCountry(1);
final Organization org = new Organization();
final User usr = new User();
given(orgRepository.save(orgInputCaptor.capture())).willReturn(Mono.just(org));
given(usrRepository.save(usrInputCaptor.capture())).willReturn(Mono.just(usr));
webTestClient.mutateWith(csrf()).post().uri(REGISTER_PATH).contentType(APPLICATION_JSON).bodyValue(register)
.exchange().expectStatus().is2xxSuccessful().expectBody();
StepVerifier.create(orgMonoInputCaptor.getValue()).expectNext(org).expectComplete();
then(usrRepository).should().save(usrInputCaptor.capture());
}
}
测试用例因 404 NOT_FOUND 错误而失败。

我错过了什么吗？
解决方法
@WebFluxTest 用于测试使用 WebFlux 基于注解的编程模型的应用程序的切片。它包括 @Controller 豆（以及其他）但不包括 RouterFunction 豆。 value 的 @WebFluxTest 属性应用于标识您要测试的特定 @Controller，而不是测试所有 @Controller bean。 @WebFluxTest({ RegistrationHandler.class }) 看起来不对，因为我认为 RegistrationHandler 不是控制器。
您应该改用 @SpringBootTest 或 @Import RouterFunction 实现，如 Spring Boot reference documentation 中所述：
@WebFluxTest 无法检测通过功能性 Web 框架注册的路由。要在上下文中测试 RouterFunction bean，请考虑通过 RouterFunction 或使用 @Import 自己导入您的 @SpringBootTest。
我错过了 WebFluxTest 注释中的 RouterConfiguration 类，添加相同后它工作正常。
@WebFluxTest({ RegistrationHandler.class,RouterConfiguration.class })
