Which of the following best describes REST Assured's capability for error handling?

• A. It cannot handle errors
• B. It has built-in error response validation
• C. It only logs errors
• D. It requires manual error checking

Answer: (B)

REST Assured provides built-in error response validation, which is a key feature for automating the testing of RESTful APIs. This capability allows testers to define expected responses for various scenarios, including successful requests and error scenarios. By validating the response codes, headers, and body of an API's error responses, REST Assured ensures that the API behaves as expected under error conditions. This functionality is crucial for QA because it not only checks for the correctness of the responses returned by the API but also allows testers to assert that the correct error codes are returned for different types of erroneous requests. For instance, if a user tries to access a resource that doesn't exist, REST Assured can validate that the API returns a 404 status code along with the appropriate error message in the response body. The presence of this built-in validation feature greatly reduces the need for additional error handling mechanisms, enhancing efficiency in the testing process. Hence, the capability of REST Assured to automate the validation of error responses makes it a powerful tool in quality assurance for APIs.
