Testing & Quality

0May 2026

Skills for test-driven development, automated testing, and quality validation across code and web applications.

What problem does this solve?

Building untested code leads to bugs that slip into production. These skills enforce test-first workflows and automated testing patterns, so your code ships with confidence and fewer defects.

How does it work?

  1. Choose your testing approach (unit tests, web UI tests, or test-driven development). 2. The skill guides you through writing tests before code (RED-GREEN-REFACTOR) or validating existing features. 3. Tests catch regressions and edge cases automatically. Output: bulletproof code with measurable test coverage.
