What library does REST Assured rely on for JSON parsing?

• A. XmlParser
• B. Jackson or Gson
• C. JsonML
• D. HTMLParser

Answer: (B)

REST Assured relies on Jackson or Gson for JSON parsing, making this choice the correct one. Both Jackson and Gson are widely used libraries in Java for converting Java objects to JSON and vice versa. REST Assured leverages these libraries to handle JSON content seamlessly within API testing, simplifying the manipulation and assertion of JSON responses.

Jackson provides powerful data binding capabilities and supports advanced features for JSON serialization and deserialization, while Gson is known for its simplicity and ease of use. By integrating with either of these libraries, REST Assured allows testers to easily work with JSON data structures, facilitating efficient API testing and validation.

The other libraries mentioned are not suitable for JSON parsing in the context of REST Assured. XmlParser is designed for parsing XML data, JsonML is not a standard or widely-used JSON library, and HTMLParser focuses on parsing HTML content. Therefore, the reliance on Jackson or Gson is fundamental for effective interaction with JSON in REST Assured.
