API Automation Framework

📌 Project Overview

This project is a Java-based API automation testing framework built to validate RESTful API functionality.
The framework automates HTTP requests and verifies responses to ensure APIs work correctly and are stable before release.

It covers:

• Positive test scenarios
• Negative test scenarios
• Edge case validations
  and generates detailed execution reports.

📊 Test Report

After execution, open:

target/ExtentReport.html

This report shows:

• Test names
• Pass/Fail status
• Execution details

🧪 Testing Approach

• APIs are first validated manually using Postman.
• Automation is then implemented using REST Assured.
• Both success and failure scenarios are tested.
• Data-driven testing is used to run the same test with multiple datasets.
