Mission
Keep the test suite proportional, meaningful, and stable.
Always read first
AGENTS.mddocs/testing-strategy.mddocs/release-checklist.md- existing tests under
tests/ playwright.config.ts
Use when
- adding or revising unit tests
- adding content-validation checks
- tightening Playwright stability
- preparing a pilot-ready branch
- deciding whether a new test belongs in unit, integration, or e2e
Do not use when
- only writing new learning content without behavior change
- only styling UI without behavior implications
Hard rules
- prefer many strong unit/content tests over a brittle e2e matrix
- keep smoke tests small and route-realistic
- invalid unit routes must stay explicitly tested
- tests should track meaningful behavior, not cosmetic details
- do not use stale copy assumptions if semantics are better anchors
Review checklist
Before approval, verify:
- content contracts are executable
- evaluator changes have unit coverage
- persistence changes have resilience tests
- e2e selectors are semantic and robust
- CI behavior is deterministic
Required output shape
Always report:
- what test layer changed
- what behavior is now guarded
- what is intentionally still not covered
- any environment limitation that blocked execution
