debugging

To debug failing tests systematically, first reproduce the failure and capture observed symptoms. Then separate confirmed facts from hypotheses, run minimal experiments to disprove leading causes, and apply a root-cause fix before focused retesting.

Root-cause analysis during bug triage involves separating symptoms from confirmed facts and unknowns. You generate hypotheses, prefer the smallest experiment that can disprove each one, and fix the underlying cause rather than the visible symptom.

Diagnose production incidents by forcing symptom capture and structured failure analysis. Document confirmed facts and hypotheses, run minimal experiments to test them, and only apply root-cause fixes once the leading hypothesis is disproven.

Reproducing a bug before fixing code prevents premature or incorrect patches. It allows you to inspect the actual failure, separate symptoms from hypotheses, and design the smallest experiment to disprove your suspected cause.

Yes, structured failure analysis is applicable to bugs, failing tests, exceptions, and production incidents across various codebases and environments. It systematically forces symptom capture, hypothesis generation, minimal experiments, and root-cause fixes.

Add or update focused tests during debugging when the bug has a clear behavioral contract. This follows applying a root-cause fix, ensuring the minimal experiment results are verified and the original failure is resolved.
