Discuss how you would test a RESTful API for proper error handling and response codes.
Tags
When discussing your approach to testing RESTful API error handling and response codes, focus on your understanding of the HTTP status codes and their meaning. Explain the importance of both positive and negative testing. For negative testing, mention how you would simulate various error conditions to see if the API responds appropriately. For positive testing, describe how you would verify that correct responses are returned under normal conditions. Discuss the tools you may use, like Postman or curl, to send requests and evaluate the responses. Make sure to highlight how you'd test for common errors like 400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found, and 500 Internal Server Error, as well as the correct implementation of successful responses like 200 OK and 201 Created.
