Support of MockRestServiceServer for WebClient [SPR-15286]

See original GitHub issue

Stéphane Nicoll opened SPR-15286 and commented

Spring Boot has a @RestClientTest for pure client-side tests. We currently auto-configure MockRestServiceServer and bind any RestTemplate created by the RestTemplateBuilder to it.

This would be pretty awesome if we could port that feature to WebClient transparently if webflux is on the classpath. That would require that MockRestServiceServer can be configured with a WebClient in addition to a RestTemplate

Using WebClient for client-side requests is pretty useless if there is no proper mock in spring for testing our code. Having rewritten my RestTemplate client code to WebClient, I’m disappointed there is no replacement for MockRestServiceServer yet…

@membersound I appreciate the point but there is also a lot of effort involved to create, maintain, and evolve something over time and it’s hard to justify given the existing alternatives. HTTP provides loose coupling so implementations can exist and evolve independently. In this case we’re even talking about mocking a server and shaping its behavior. I should think that switching from one to another shouldn’t be as big a deal as it might seem at first. That said MockWebServer has more stars than the Spring Framework does and I don’t think it is going to be a problem with longevity.
