Testing Pattern Quality Skill

Overview

This skill identifies and fixes common testing mistakes across unit, integration, and E2E test suites. Tests should verify behavior, be reliable, run fast, and fail for the right reasons.

Scope: This skill focuses on improving test quality and reliability. It complements test-driven-development by addressing what goes wrong with tests, complementing how to write them correctly from scratch.

Out of scope: Writing new tests from scratch (use test-driven-development), fixing fundamental architectural issues (use systematic-refactoring), or profiling test performance with external tools.
