test spring 5 reactive rest service

I'm using SpringBoot 2 and Spring 5 (RC1) to expose reactive REST services. but I can't manage to write unit test for those controllers.

Here is my controller 

@Api
@RestController
@RequestMapping("/")
public class MyController {

    @Autowired
    private MyService myService;


    @RequestMapping(path = "/", method = RequestMethod.GET)
    public Flux<MyModel> getPages(@RequestParam(value = "id", required = false) String id,
            @RequestParam(value = "name", required = false) String name) throws Exception {

        return myService.getMyModels(id, name);
    }
}

myService is calling a database so I would like not to call the real one. (I don't wan't integration testing)

Edit :

I found a way that could match my need but I can't make it work :

@Before
    public void setup() {

        client = WebTestClient.bindToController(MyController.class).build();

    }
@Test
    public void getPages() throws Exception {

        client.get().uri("/").exchange().expectStatus().isOk();

    }

But I'm getting 404, seems it can't find my controller

You have to pass actual controller instance to bindToController method. As you want to test mock environment, you'll need to mock your dependencies, for example using Mockito.

public class MyControllerReactiveTest {

    private WebTestClient client;

    @Before
    public void setup() {
        client = WebTestClient
                .bindToController(new MyController(new MyService()))
                .build();
    }

    @Test
    public void getPages() throws Exception {
        client.get()
                .uri("/")
                .exchange()
                .expectStatus().isOk();
    }

}

More test examples you can find here.

Also, I suggest switching to constructor-based DI.
