Document that RouterFunction beans in the context cannot be used with @WebFluxTest

@wilkinsona those are usually defined within a @Configuration class so I am wondering how we would detect that.

[wilkinsona]

And now that you've asked, I'm wondering too. Without support in the Framework for filtering the beans produced by a configuration class that's similar to the filtering offered for component scanning, I can't think how we can do it.

[snicoll]

It's worse than that even. The router is linked to one or more handlers. I think a good match in that world would be to split routers per area and the slice is the router.

But even if you have that you need to add the handler beans. And those are regular components with methods in them. So we would have to scan the injection point upfront to add them. Sounds quite complicated.

@wilkinsona removing from the 2.0 bucket as I don't see a way to implement this at the moment. Worth considering in par with the "programmatic/explicit configuration"

Hello there !
Any news about this point ? I am not using controller but new functional endpoints. Will be really awesome to use WebFluxTest.
Thank you !

No news at this time (this issue would have been updated if there was). As things stand, we don't think it's possible to do what we'd like, certainly not without some changes in Spring Framework and maybe not at all.

If it can help people who are using functional endpoints as I do. I so finally test them by this way :

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {RouteConfiguration.class, UserHandler.class})
@WebFluxTest
public class UserHandlerTest
{
    @Autowired
    private ApplicationContext context;
    @MockBean(name="userService")
    private UserService userService;
    private WebTestClient testClient;

    @Before
    public void setUp()
    {
        testClient = WebTestClient.bindToApplicationContext(context).build();
    }

    ...

The WebFluxTest annotation keep avoid to load other things than RestController and I customize the ContextConfiguration to load my functional endpoints.

Hello there!

I tried the below and It works for me.

@WebFluxTest(controllers = {RouteConfiguration.class, UserHandler.class})
public class UserHandlerTest {
   @Autowired
   private WebTestClient testClient;

   @MockBean(name="userService")
   private UserService userService;
...
}

}

I confirm. My Boot is at 3.2.3
