Support HTTP Interface Clients in Test Framework

From: https://docs.spring.io/spring-framework/reference/integration/rest-clients.html#rest-http-service-client

[start quote]

On the server side, an @Controller class can implement the same interface to handle requests with @HttpExchange controller methods.

[end quote]

At the moment, there are WebTestClient and RestTestClient for REST Testing. However, it may be beneficial to use HTTP Interface clients for testing where WebTestClient and RestTestClient assertions are not needed.

At the moment, I see no way to instantiate HTTP Interface Clients and bind them to test Web Server in conjunction with SpringBootTest.WebEnvironment.RANDOM_PORT.

Would you be interested in providing any kind of support for using HTTP Interface Clients within Test Context?

At least consider providing HttpExchangeAdapter for WebTestClient and RestTestClient.

Thanks in advance.
