What is the advantage of using REST Assured for testing?

• A. It only works with SQL databases.
• B. It allows customization of HTTP requests.
• C. It is limited to XML responses only.
• D. It can be used for UI testing.

Answer: (B)

Using REST Assured offers significant advantages, particularly in its ability to customize HTTP requests. This feature is vital for testing RESTful APIs, as it enables testers to specify various components of the request, such as headers, parameters, and body content according to the needs of the API being tested. Such flexibility allows for comprehensive testing scenarios, where specific aspects of requests can be altered to observe how the API responds under different conditions.

Additionally, REST Assured seamlessly supports different types of HTTP methods like GET, POST, PUT, and DELETE, which are essential for interacting with a wide array of API endpoints. This level of customization is a major reason why it is favored in automated API testing, allowing users to efficiently verify responses, validate data, and confirm the expected behavior of the API across various use cases.
