How can you extract a JSON value from a response in REST Assured?

• A. By using the getJson() method
• B. By using the jsonPath() method
• C. By using the extract() method
• D. By parsing the response directly

Answer: (B)

The jsonPath() method is the correct approach for extracting a JSON value from a response in REST Assured because it allows you to navigate through the structure of the JSON response easily. With jsonPath(), you can specify a path to the desired value using a syntax similar to that used in XPath for XML. This method enables the extraction of values based on their key or position, making it very efficient for working with complex JSON structures. For instance, if the JSON response contains multiple nested objects, jsonPath() can facilitate direct access to the specific node or value you need without requiring iterative searches or manual parsing. This is a powerful feature when writing tests for RESTful services, as it enhances the clarity and maintainability of the test code. Other methods mentioned, such as getJson(), may not be standard in the REST Assured library, extract() is typically used to retrieve response data objects rather than directly for JSON value extraction, and parsing the response directly would involve more complex code and string manipulation, which is not as efficient or straightforward. Thus, jsonPath() stands out as the most effective method for this task.
