What information is usually described in the specification when using REST Assured for API testing?

In the specification, when using REST Assured for API testing, it usually describes:

• URL and endpoints: the addresses of the APIs to be tested.
• HTTP methods: GET, POST, PUT, DELETE, etc.
• Request parameters: query parameters, headers, request body.
• Expected responses: status codes, response structure and content (JSON, XML).
• Test conditions and scenarios: positive and negative cases.
• Authorization and authentication: methods of accessing the API.

An example of a specification may include a description of the request with headers and the expected JSON response, which helps in writing more structured and understandable tests with REST Assured.
