🧪 Software Quality Assurance (SQA) Lifecycle Implementation

📌 Overview

This repository contains the complete implementation of the Software Quality Assurance (SQA) Continuous Assessment Labs for my Master's Degree Programme.

The project demonstrates a full Software Quality Assurance lifecycle, covering testing, version control, release management, and performance validation using industry-standard tools and workflows.

The labs simulate a real-world banking software development environment, applying professional engineering practices throughout the development lifecycle.

🎯 Purpose of the Repository

This repository was created to demonstrate practical implementation of Software Quality Assurance principles including:

✅ Unit Testing

✅ Integration Testing

✅ Version Control & Configuration Management

✅ Git Branching Strategy (GitFlow Simulation)

✅ Release Management & Version Tagging

✅ Performance & Load Testing

The project showcases how testing, version control, and performance validation integrate within a real software development workflow.
