Ai Regression Testing

affaan-m/ecc

Summary

When the same AI writes code and reviews it, you get systematic blind spots. This skill addresses that with regression testing patterns built for AI-assisted development. The core workflow is simple: run tests before AI review, catch sandbox/production path mismatches mechanically instead of relying on model judgment, and write regression tests for every bug found. The documentation walks through real patterns from production where AI missed the same bug four times in code review but a single test caught it instantly. Most valuable if you have a sandbox mode for database-free API testing and you're using Claude or similar models to modify backend routes.
