What utility can you use to validate JSON schema against a specification in REST Assured?

• A. JsonValidator
• B. JsonSchemaChecker
• C. JsonSchemaValidator
• D. JsonAssert

Answer: (C)

The reason why the answer is JsonSchemaValidator is that it is specifically designed to validate JSON data structures against defined schemas in REST Assured. This utility supports the validation process by allowing you to ensure that the JSON response from an API adheres to a particular format specified in the schema, making it straightforward to check the correctness of the response.

Utilizing JsonSchemaValidator enables developers and testers to easily conduct automated checks that verify whether the API responses are conforming to the expected data structures, enhancing the robustness of API testing. By leveraging validation against a schema, any discrepancies in the data format can be quickly identified and addressed.

Other alternatives, such as JsonValidator, JsonSchemaChecker, and JsonAssert, serve different purposes or do not exist in the context of REST Assured schema validation. JsonValidator does not specifically focus on schema validation, while JsonAssert primarily deals with asserting JSON values rather than schema compliance. JsonSchemaChecker does not exist as a designated utility for this purpose, making them less suitable for validating JSON schema against specifications effectively.
