What is a key REST advantage in terms of developer response and testing?

• A. REST requires complex, stateful client setup
• B. REST uses heavy payloads that require complex tooling
• C. REST APIs are rarely tested
• D. REST enables independent, stateless requests and simpler testing with tooling

Answer: (D)

REST’s stateless design means every request carries all the information needed, so calls are independent and can be processed without server-side session data. This makes testing straightforward: you can hit endpoints directly with lightweight tooling (curl, Postman, automated tests) and verify responses without managing complex user sessions. The lack of server-side state also enables easier scaling and repeatable tests, since each request is self-contained. In practice, this combination of independent, stateless requests and simple testing tools is the main advantage for developers.
