To systematically debug software errors, follow a structured process: reproduce the error, classify it by type and severity, isolate the root cause, implement a fix with a test, and document the solution in error-log.md.

The best way to classify software errors during troubleshooting is by type—Syntax, Runtime, Logic, Integration, or Performance—and severity level, ranging from Critical to Low. This classification prioritizes debugging efforts effectively.

To use regression testing when fixing bugs, write a failing test that reproduces the error first, implement the fix to make it pass, and add the test to your suite. This ensures stability and prevents future recurrence.

You should maintain an error-log.md for bug fixing to enable historical tracking and knowledge sharing. Documenting the error classification, root cause analysis, and fix implementation prevents similar issues and builds team debugging knowledge.

Yes, you can use binary search to isolate runtime errors by systematically narrowing down the codebase sections where the error originates. This isolation method helps pinpoint the exact location of the bug efficiently.
