What Is the Use of WebClient and WebTestClient?

WebClient is a component in the new Web Reactive framework that can act as a reactive client for performing non-blocking HTTP requests. Since it's reactive client, it can handle reactive streams with back pressure, and it can take full advantage of Java 8 lambdas. It can also handle both sync and async scenarios.

On the other hand, the WebTestClient is a similar class that we can use in tests. Basically, it's a thin shell around the WebClient. It can connect to any server over an HTTP connection. It can also bind directly to WebFlux applications using mock request and response objects, without the need for an HTTP server.
