📖 About

API Engineering Lab is a structured repository demonstrating professional API testing practices using modern QA engineering tools and methodologies.

The objective is to build a production-inspired knowledge base covering:

• REST API Testing
• API Automation
• Authentication & Authorization
• Data-Driven Testing
• Performance Testing
• CI/CD Integration
• Python API Automation
• Best Engineering Practices

This repository is maintained as a long-term engineering reference rather than a collection of tutorials.
