REST Assured

Rest-Assured is a popular Java-based library for testing RESTful web services, known for its simplicity and power. It allows testers to write readable and maintainable tests without requiring extensive coding knowledge, making it accessible for both developers and QA engineers.

Testing and validating REST services in Java is harder than in dynamic languages such as Ruby and Groovy. REST Assured brings the simplicity of using these languages into the Java domain.

Key Features:

• Fluent API: Rest-Assured offers a fluent API, enabling easy creation and chaining of requests and assertions, resulting in highly readable tests.
• BDD Support: It supports Behavior Driven Development (BDD) style syntax using Gherkin, which helps in making tests more understandable for non-technical stakeholders.
• Seamless Integration: It integrates well with Java testing frameworks like JUnit and TestNG, making it suitable for various test environments.
• Authentication Support: Rest-Assured simplifies handling different authentication mechanisms, including OAuth, basic authentication, and form authentication.
• JSON and XML Parsing: The library provides robust support for JSON and XML parsing, making it easy to validate responses.
• Request Specification Reuse: It allows the reuse of request specifications, which promotes the DRY (Don't Repeat Yourself) principle and reduces boilerplate code.

Overall, Rest-Assured is a powerful tool that enhances the efficiency and readability of API tests, making it a valuable asset for any development team working with RESTful services.
