E2E Playwright + Lighthouse Tester

Use this skill to run reproducible e2e and Lighthouse checks across a target web repo, with discovery-first command selection and clear reporting.

Workflow

1. Discover first

• Run:
• python3 .cursor/skills/tester/scripts/discover_audit_targets.py .
• Optional JSON output: python3 .cursor/skills/tester/scripts/discover_audit_targets.py . --json
• Read discovered package scripts, runner files, and PWA signals before deciding what to run.

1. Runner selection priority

• Prefer existing npm / pnpm / yarn scripts that already run Playwright and Lighthouse.
• Otherwise use checked-in runner files in common locations (perf/, scripts/, e2e/, tests/).
• Only use ad-hoc npx playwright / npx lighthouse commands if no native runner exists.

1. Execution matrix

• For Lighthouse, target all slices when technically possible:
• light-desktop
• light-mobile
• dark-desktop
• dark-mobile
• Attempt categories:
• performance
• accessibility
• best-practices
• seo
• pwa (when supported by installed Lighthouse and app signals)
• Prefer preview or production-like mode instead of noisy local dev mode when the repo supports it.

1. 100/100 objective

• Always optimize toward 100/100 in Lighthouse categories and Web Vitals-related audits.
• Do not claim false success; explicitly list blockers and remaining deltas to 100.

Reporting contract

Always report by package/surface:

• Commands run, including whether native or adapted.
• Playwright findings: failing flows, flaky clues, console/page errors, failed requests, auth blockers.
• Lighthouse findings per matrix slice (light-desktop, light-mobile, dark-desktop, dark-mobile).
• A dedicated 100/100 gap analysis section with highest impact opportunities.
• Explicit coverage gaps (skipped routes, no dark mode, no mobile emulation, missing credentials, unsupported PWA category).

Guardrails

• Keep commands non-interactive whenever possible.
• Never silently skip a matrix slice; report why it was skipped.
• If the repository is not a web app, stop quickly and state that no web target was detected.
