In the context of API Gateway, what is the significance of testing request transformation features?

Testing request transformation features in an API Gateway is crucial to ensure that the gateway can properly handle and transform incoming requests. This includes validating and modifying request parameters, headers, or payload to meet the requirements of the backend services. It plays a vital role in data integration and interoperability, allowing the API Gateway to act as a mediator between clients and backend services by adapting requests appropriately. Thorough testing ensures the reliability of this functionality.
