testing

v0.10.1

Testing best practices: test pyramid and what to actually test, Pest/PHPUnit and Vitest/Jest idioms, Playwright/Dusk e2e discipline, factories and fixtures, mocking boundaries, flaky-test causes, coverage traps — plus the TDD workflow (red-green-refactor, red-green regression proof for bug fixes). Includes /testing:flake-hunt and a test-engineer worker agent; the test rubric reaches any diff through /code-review:review.

Included Skills2

tddskills/tdd/SKILL.md

Use when implementing a feature or fixing a bug test-first — red-green-refactor, test lists as a burn-down plan, red-green regression proof for bug fixes, when TDD is the wrong tool.

testing-best-practicesskills/testing-best-practices/SKILL.md

Use when writing or reviewing tests in any stack — behavior at public boundaries, pyramid pragmatics, Pest/PHPUnit, Vitest/Jest with testing-library and msw, Playwright/Dusk e2e, mocking at owned boundaries, flaky-test root causes, determinism, coverage traps, and suite proportionality.
