Difference between debugging and testing explained

📚 Quick Study Guide

• 🔍 Testing: Verifies if the software meets specified requirements and works as expected. It's about finding defects.
• 🧪 Debugging: The process of identifying and fixing the found defects. It comes *after* testing has revealed a problem.
• ⏱️ Timing: Testing is typically done throughout the development lifecycle, while debugging is triggered by test failures.
• 🛠️ Goal: Testing aims to uncover failures; debugging aims to resolve them.
• 💡 Tools: Testers use test cases and automation tools; debuggers use debuggers and log files.
