B5 of TEST-INFRA-001 (RFC-WS-FRONTEND-PRIMEVUE Amendment A-1).
- Add dev-docs/ARCH-TESTING.md (~13 KB):
§1 Five-tier pyramid (Unit / Component / Integration / Visual /
E2E) with environment, cost, and purpose per tier
§2 Decision tree — pick by what is being verified, not by speed
§3 Mock-vs-real-backend rules + the self-confirming-bias anti-
pattern that motivated TEST-CONTRACT-001
§4 Visual baseline workflow including the composite-over-isolated
strategy used in B3
§5 CI strategy stub — deferred to TEST-INFRA-002
§6 Conventions + 5 anti-patterns
§7 Vuetify-during-PrimeVue-migration: explicit doc that the
Vuetify plugin in playwright/index.ts is INTENTIONAL TEMPORARY
STATE replaced in F3 by PrimeVue. Forbids the "abstract the UI
framework provider" deferred-cost trap.
§8 Host setup — Node, pnpm, Chromium, Git LFS, MySQL 8, PHP, .env;
known risks (unpkg.com flakiness, shared crewli_test DB)
§9 Deferred work cross-references to BACKLOG entries
- Update CLAUDE.md ### Testing section to reference ARCH-TESTING.md
- Add ARCH-TESTING.md to .claude-sync.conf so the dev-docs sync
pipeline picks it up; sync script run.
