Debugging

Comprehensive debugging methodologies, tools, and techniques across languages and platforms.

Systematic Debugging Methodology

Every debugging session should follow a disciplined, repeatable process. Resist the urge to change code at random.

The Five-Step Process

1. Reproduce - Create a reliable way to trigger the bug every time.
2. Isolate - Narrow the scope until you find the smallest reproducible case.
3. Identify - Determine the root cause, not just the symptom.
4. Fix - Apply a targeted correction that addresses the root cause.
5. Verify - Confirm the fix works and does not introduce regressions.
