Configure RSocket standalone servers with a local transport for tests #18387

In the web world, we configure a mock environment instead of starting a real web server for integration tests, with the following:

@SpringBootTest(webEnvironment = WebEnvironment.MOCK)

It would be nice to explore whether we can configure a local transport (rsocket-transport-local) to test interactions between an RSocket server and an RSocket client. This might require changes in Spring Framework with the RSocketRequester, or test infrastructure to make things easier.

This would be extremely useful for the Gateway RSocket Broker. Can't wait to see what you come up with. Let me know if I can help.

Hi, I was thinking about the testing support for RSocket las week and at high level this is the list

RScocketRequesterTestClient in spring-framework, similar to WebTestClient but using RSocketRequester.
RSocketServiceServer in spring-framework, similar to MockRestServiceServer
@RSocketClientTest for slice testing in spring-boot, which allows to autowire RScocketRequesterTestClient to perform requests and assertions against RSocketServiceServer.
@RSocketTest to enable de infrastructure for RSocket, similar to @WebFluxTest or @WebMvcTest
