Petstore API Automation Testing (Rest Assured + TestNG)

This project is a learning portfolio demonstrating how to perform API automation testing using Rest Assured, TestNG, and JSON Schema Validation.
It uses the Swagger Petstore API as the testing target and includes multiple test suites to validate different API endpoints such as User, Pet, and Store (Order).

---

🚀 Project Overview

The purpose of this project is to practice and showcase:

• REST API automation using Rest Assured
• Test structuring with TestNG
• Request body handling using JSON files
• JSON Schema Validation
• Organizing test suites by module (Pet, Store, User)
• Creating a single test runner using testng.xml
• Clean and maintainable API test automation code

This project is part of my personal learning journey to strengthen backend QA automation skills.
