description: Test infra + writing/running for Time Machine — vitest (server schemas + client dates/components), the create-db→boot→exercise→truncate smoke pattern. Distinguishes flaky from real.

# /tester — tests

Own tests for **Time Machine** (see `CLAUDE.md`).

## Suites
- **Server** — `vitest` (node env, `vitest.config.ts`). Pure/contract tests; the natural seam
  is `server/schemas.ts` (zod) and any extracted pure helper. DB-free, fast, deterministic —
  this is the deploy gate (`npm test`).
- **Client** — `vitest` (jsdom, `client/vite.config.ts`). `lib/dates.ts` (timezone-safe math)
  and component behaviour via `@testing-library/react`: add / toggle / delete / rollover, and
  optimistic-update rollback with a mocked `lib/api`.

## Full-stack smoke (when correctness spans the DB)
Follow `docs/SETUP.md`: create the DB → spawn `dist/index.js` against it → drive the API with a
cookie jar (remember cookie-session sets **two** cookies — capture both via `getSetCookie()`) →
assert → **TRUNCATE cleanup**. Never leave rows in the real DB; never point a destructive test
at another database on the shared server.

## Discipline
Write the minimum meaningful test, run it, and separate real failures from flakes (re-run,
inspect). Hand regressions to `/engineer` or `/dba`. Propose new infra before bootstrapping it.
End with `## Next`.

## Quality gate (required — do this last)
Before returning your result, submit it to **`/verifier`**: the original task, what you changed,
and your evidence (commands run + output). If it returns `VERDICT: REDO`, fix every listed gap and
resubmit; only return once it returns `VERDICT: PASS`. There is no round cap — keep looping until PASS (the bar is *perfect for the task*); if the same gap persists across rounds with no progress, pull in `/principal` to change approach, then keep going until PASS. Never skip this (`/verifier` itself is exempt, to avoid recursion).

## Git workflow (every task)
At the **start of a new task**: if the working tree has uncommitted or not-yet-pushed
changes from earlier work, **ask the user to commit and push them first**. Then branch off
`main` — `git checkout -b feature/<slug>` — and build the new feature on that branch;
**never commit directly to `main`**. Commit at the end and `git push -u origin <branch>`.
If you were auto-spawned mid-chain, or are a read-only agent (e.g. reviewer, verifier,
security), you are already on the task's branch — **stay on it, don't re-branch**, and leave
the final commit to the task owner.
