# TESTS — F-002 Database foundation with module-owned schemas

## Integration (Vitest, `*.itest.ts`, run with TEST_DATABASE_URL set)
- `migrations.itest.ts`:
  - fresh database + `migrate up` → `app_meta` exists
  - second `migrate up` → no-op (no errors, same state)
  - `migrate down` → `app_meta` gone
- `pool.itest.ts`:
  - `createPoolFromEnv` connects and `SELECT 1` roundtrip
  - insert/read/delete row in `app_meta` via query helper

## Manual/CI commands
- `npm run docker:up` starts PostgreSQL + Redis with one command
- `npm run db:up` on fresh DB exits 0; second run exits 0 with nothing applied
- `npm run db:down` exits 0 and drops baseline objects
- `npm test` stays green even without TEST_DATABASE_URL (integration tests skip explicitly)

## Acceptance traceability
| Criterion | Evidence |
|---|---|
| fresh up creates schema, rerun is no-op | migrations.itest.ts + db:up twice in implementer.md |
| down rolls back cleanly | migrations.itest.ts + db:down output |
| naming convention documented/enforced | README section + baseline migration exemplar |
| dev DBs start with one command | docker compose up output |
| verify.sh green | qa.json evidence |
