Which of these is a common response format that REST Assured can validate?

• A. CSV.
• B. XML.
• C. HTML.
• D. Text files.

Answer: (B)

The correct answer is XML, which is a common response format that REST Assured can easily validate. REST Assured is designed to interact with RESTful web services and has built-in support for various data formats, among which XML is prominent.

XML, which stands for eXtensible Markup Language, is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. REST Assured enables you to parse XML responses using its powerful and intuitive testing capabilities. This includes using XPath to navigate through XML documents and validate specific elements and values, ensuring that the API provides the expected structure and content in its responses.

While CSV, HTML, and text files can be part of other testing scenarios, they do not have the same level of direct support and functionality within REST Assured as XML does. CSV typically involves handling flat file structures where each line is a data record, which is outside the primary use case of REST Assured. HTML responses can be parsed, but they are often not structured data in the same way XML is, making validations more cumbersome. Additionally, text files are essentially unstructured and would not benefit from the specific XML validation capabilities that REST Assured provides. Therefore, XML stands out as the most
