| description | Use when user has fixed a bug and needs a test that proves it stays fixed, or when a failure needs to be captured as a reproducible test case. |
Kaboom Regression Test
Use this skill after a bug is confirmed and should never reappear.
Inputs To Request
- Failure scenario and expected outcome
- Test layer preference (unit, integration, e2e)
- Existing test file or suite location
Workflow
-
Reproduce failure deterministically:
Capture exact trigger and expected assertion.
-
Pick narrowest test layer:
Prefer unit/integration before full e2e unless browser behavior is required.
-
Build stable fixtures:
Use fixed inputs, bounded timing, and mocked unstable dependencies.
-
Write fail-first assertion:
Ensure test fails on pre-fix behavior and targets the real defect.
-
Add guard assertion:
Assert adjacent behavior to prevent overfitting.
-
Verify repeatedly:
Run targeted tests multiple times to catch flakiness.
