Testing

The spring-test module provides mock implementations of ServerHttpRequest, ServerHttpResponse, and ServerWebExchange. See Spring Web Reactive for a discussion of mock objects.

WebTestClient builds on these mock request and response objects to provide support for testing WebFlux applications without an HTTP server. You can use the WebTestClient for end-to-end integration tests, too.
