I want to know if there is any difference between request().get(url) and request().request(Method.GET,url) in RestAssured.
When I try to do get() both seem to working same.
No, functionally they are the same, it's a matter of style. Both call the private method
applyPathParamsAndSendRequest(String method, String path, Object... unnamedPathParams)
You can choose one to match your code style.
