API Testing with Rest-Assured

This repository demonstrates how to automate API testing using Rest-Assured, focusing on parameterization, request/response specifications reuse, and object serialization.

Requirements

• JDK 11 or higher
• Maven (for dependency management and build)

API Used for Demonstration

• REQRES API: https://reqres.in/

Scenarios Covered

• Parameterizing Rest-Assured Test Cases with Data Provider: Implemented to run tests with multiple sets of data, improving test coverage and re-usability.
• Reuse Request and Response Specifications: Optimized API test cases by using predefined request and response specifications to eliminate code duplication.
• Serializing a Java Object to a JSON Request Body: Demonstrates converting Java objects to JSON format and sending them in the request body for API testing.

Project Structure

• src/main/java: Contains POJO's and configuration class.
• src/test/java: Contains the Rest-Assured test classes, test data provider, and configurations for request and response specifications.

Features

• Parameterized API tests using TestNG Data Providers.
• Re-usability through Request and Response Specification.
• POJO Serialization for sending structured data in requests.
