Testing And Quality

skill-martian56-claude-engineer-testing-and-quality · by martian56

Use throughout the build and before claiming any phase or the project "done", to run the four mandatory quality gates and verify them with evidence. Covers the test pyramid, Playwright + Chrome DevTools browser verification, WCAG AA, and the commit/finish gate wiring.

About

Testing & Quality

Announce at start: "I'm using claude-engineer:testing-and-quality to enforce the four quality gates."

Iron Law

No "done" without all four gates passing, verified by fresh evidence. (Pairs with superpowers:verification-before-completion - assertions follow evidence, never precede it.)

The four gates (exact pass/fail commands; exit 0 = pass)

  1. Tests + coverage - FE vitest run --coverage; BE pytest --cov=app --cov-fail-under=80.
  2. E2E + zero console errors - playwright test (specs include a console-error/pageerror fixture and assert no 4xx/5xx on key routes). Drive flows and confirm every button/screen works via the Playwright + Chrome DevTools MCPs.
  3. Accessibility (WCAG AA) - playwright test a11y/ using @axe-core/playwright with tags wcag2a,wcag2aa,wcag21aa,wcag22aa; assert zero violations. Manual keyboard/focus spot-checks too.
  4. Strict types + lint clean - tsc --noEmit && eslint . && prettier --check . && ruff check . && ruff format --check . && mypy app.

The gate runner + commit gate

  • Scaffold scripts/quality-gate.mjs from templates/quality-gate.mjs. It runs all four gates and writes

.claude-engineer/quality-gate-status.json ({ allPass, results }).

  • The claude-engineer PreToolUse(Bash) hook blocks git commit unless that file shows allPass: true.

So: run node scripts/quality-gate.mjs → fix failures → commit. Intentional bypass: git commit --no-verify.

  • The same four commands are the finish condition and the CI merge condition (claude-engineer:ci-cd-pipeline).

Browser verification (MCPs - BYO install)

  • Chrome DevTools MCP - capture/assert zero console errors per screen, Lighthouse audits, network-failure checks.
  • Playwright MCP - drive real flows; confirm interactions actually work.

Install per templates/recommended-mcps.md.

Full detail (test pyramid, coverage targets, Playwright setup, the console-error fixture, axe usage, exact commands): read references/testing-and-gates.md on demand.

Red flags - STOP

  • Claiming "done"/"passing" without re-running the gate now.
  • Committing with a failing/stale gate (use --no-verify only with explicit reason).
  • Treating console warnings/errors as acceptable - the E2E gate requires zero.
