How can you assert that a JSON response has a specific content type?

• A. By using the type() method
• B. By using the validateContent() method
• C. By using the contentType() method
• D. By using checkContent() method

Answer: (C)

The contentType() method is specifically designed for validating the content type of a response in REST Assured. When you are working with REST APIs that return JSON responses, it is crucial to ensure that the returned content matches the expected media type, such as "application/json". This method allows you to assert the exact content type, which helps in verifying that the API behaves as expected and that the response data can be properly processed. Using contentType() provides a clear and intuitive way to check the HTTP headers of the response. If the response does not match the specified content type, the assertion will fail, alerting you to a potential issue with the API. Other methods listed do not serve this specific purpose. For instance, the type() method is typically used for extracting the response type but does not focus on asserting content type. ValidateContent() and checkContent() methods are not recognized standard methods within REST Assured, which specifically undermines their applicability in this context. This highlights why contentType() is the correct and relevant choice for asserting the JSON response's content type.
