Testing MVC controller using reactor with WebClient












1















@RestController
@RequestMapping("/api/v1/platform")
public class PlatformController {

@Autowired
private PlatformRepository platformRepository;


@GetMapping
public Flux<Platform> findAll() {
log.info("Calling findAll platforms");
return platformRepository.findAll();
}
}


@RunWith(SpringRunner.class)
@WebFluxTest
public class PlatformControllerTest {

@MockBean
private PlatformRepository platformRepository;


@Test
public void findAll() throws Exception {
WebTestClient client = WebTestClient.bindToController(new PlatformController()).build();
client.get()
.uri("/api/v1/platform")
.exchange()
.expectStatus().isOk();
}

}


Above I have attached a simple POC of what i want to achieve. I am unable to inject the mock into the controller for my tests and the tests fails. Is there any other way to do this or am i missing some fundamental concept?

          Things started to work after i added the controller class to the context configuration.



          @RunWith(SpringRunner.class)
          @ContextConfiguration(classes = {
          PlatformController.class,
          MongoTestConfig.class
          })
          @WebFluxTest(PlatformController.class)


          I think it could be a bug, as the controller should be in the context after being included in the WebFluxTest annotation.

            From the docs:




            @WebFluxTest auto-configures the Spring WebFlux infrastructure and
            limits scanned beans to @Controller, @ControllerAdvice,
            @JsonComponent, Converter, GenericConverter, and WebFluxConfigurer.
            Regular @Component beans are not scanned when the @WebFluxTest
            annotation is used.




            Could you try to add your controller class inside WebFluxTest annotation?



            @WebFluxTest(PlatformController.class)

            • Unfortunately that does not help. I have tried another approach as well. I tried adding the @WebFluxTest(PlatformController.class) and tried to Autowire WebTestClient. In that case it does not even call the controller. It replies back with a 404. – Nandagopal Sekar 23 secs ago edit
