Debugging Best Practices for Developers

Debugging is an essential part of the development lifecycle. Here are some proven strategies to help you troubleshoot efficiently:

🔧 Use Logging Strategically

  • Implement detailed logs to track application flow and state changes
  • Use different log levels (DEBUG, INFO, WARNING, ERROR) for clarity
  • Avoid over-logging to prevent performance overhead

📄 Write Unit Tests

  • Test individual components in isolation to identify issues quickly
  • Use mocking frameworks to simulate complex dependencies
  • Maintain a test suite that covers all edge cases

🧩 Reproduce the Problem Systematically

  • Follow the "5 Whys" technique to uncover root causes
  • Use version control to isolate code changes
  • Document steps to recreate the issue for team collaboration
