Features of Rest Assured Framework

 

What is Rest Assured?

• Rest Assured is an open-source Java library designed specifically for testing RESTful web services (APIs).
• It simplifies the process of sending HTTP requests (like GET, POST, PUT, DELETE) and validating responses without requiring a lot of boilerplate code.
• Instead of writing complex HTTP client code, testers can write concise, readable, and maintainable API tests.
• It provides a domain-specific language (DSL) for writing readable, maintainable, and expressive API test cases.

Why Rest Assured is Used

• To automate API testing efficiently.
• To verify functionality, performance, and security of APIs.
• To reduce manual testing effort (compared to tools like Postman).
• To ensure APIs return correct status codes, headers, and data.

Below are some key features of Rest Assured Framework:

Feature	Description
HTTP Methods Support	Supports GET, POST, PUT, PATCH, DELETE, OPTIONS, HEAD.
Request Customization	Allows adding headers, query parameters, path parameters, cookies, and body data easily.
Response Validation	Provides easy methods for verifying status code, headers, content types, response body, etc.
JSON & XML Parsing	Built-in support for parsing and asserting on JSON and XML responses.
Authentication	Supports Basic, Digest, Form, OAuth1, OAuth2, and custom authentication.
Integration	Can be used with JUnit, TestNG, Cucumber, and other Java testing tools.
Logging	Supports logging request and response data for debugging purposes.
Schema Validation	Can validate responses against JSON/XML schema.
Serialization/Deserialization	Easily works with POJOs using libraries like Jackson or Gson.
