Editing SpringBoot (section)

====TestRestTemplate====
* TestRestTemplate is part of the Spring Boot Test module and provides a high-level, programmatic way to test RESTful services by making actual HTTP requests to the service. It allows you to send HTTP requests (GET, POST, PUT, DELETE, etc.) to your application's REST endpoints and receive actual HTTP responses. 
* It starts an embedded server (typically an embedded Tomcat or Jetty instance) and sends requests to the server as if they were real HTTP requests. 
* TestRestTemplate is more suitable for integration testing and end-to-end testing because it interacts with the running server, making actual network calls.
