How do you send form data in a POST request using REST Assured?

• A. By using the jsonParam() method
• B. By using the formParam() method
• C. By using the body() method
• D. By using the queryParam() method

Answer: (B)

To send form data in a POST request using REST Assured, the formParam() method is employed. This method is specifically designed for adding form parameters to the request body, formatting the data in a way that is expected by servers processing form submissions. When you utilize formParam(), REST Assured automatically sets the appropriate content type for the request as "application/x-www-form-urlencoded," which is the standard for form submissions.

This method allows you to define key-value pairs that represent your form data, mirroring how form data is typically structured. For instance, if you were sending username and password as part of a login form, using formParam() would let you add those parameters directly.

In contrast, the other methods serve different purposes. The jsonParam() method is used for sending JSON data, which is structured differently than form data. The body() method allows you to send a request body directly, but it requires you to construct the body data manually, which may not align with the expectations of a form submission. The queryParam() method is intended for URL query parameters and is not suitable for sending data in the body of a POST request.

Therefore, using formParam() is the most appropriate choice for sending form data in a POST request when
