What is a primary advantage of using REST Assured in testing?

• A. It is visual and easy to use.
• B. It supports only one format of data.
• C. It provides an easy approach to validate REST services.
• D. It requires extensive setup for every test.

Answer: (C)

The primary advantage of using REST Assured in testing lies in its ability to provide an easy approach to validate REST services. REST Assured is specifically designed for testing RESTful web services, which means it simplifies the process of creating and executing tests without needing to handle the complexities that often accompany API testing.

The framework's fluent and intuitive API allows testers to focus on what they are trying to validate rather than the underlying mechanisms of sending requests and processing responses. This enhances productivity and helps in quickly validating the behavior of APIs by allowing the use of straightforward syntax for making requests, asserting responses, and validating specific aspects of the data returned.

This ease of use is particularly valuable in Agile environments where rapid development cycles require efficient testing practices. Through its ability to seamlessly integrate with other testing frameworks and tools, REST Assured promotes faster feedback and ensures higher quality in REST API services.
