# Testing

## Test Strategy

Three layers, all local-database-only (see `local-database` skill; tests refuse any database not ending in `_test`):

- **Unit** (`tests/unit/**/*.unit.spec.ts`, 47 specs as of 2026-07-25 (tooling guards)): pure logic; runs with a deliberately invalid `DATABASE_URL` so nothing can touch a database.
- **Integration** (`tests/int/**/*.int.spec.ts`, 48 specs): real Payload + Postgres (`teqo_test`); campaign fixtures allocate seeded municipalities via a Postgres sequence so parallel spec files never share one, and purge residue on claim. Shared consent rows with stable keys are leased (`tests/helpers/testDatabaseLease.ts`), never owned.
- **E2E** (`tests/e2e`, Playwright, 7 specs): smoke-level; most campaign behavior is pinned at the int layer.

CI (`.github/workflows/ci.yml`) runs lint (zero warnings), typecheck, knip, unit, migrate, int against a Postgres 17 service.

## Characterization Backlog

- [ ] `src/utilities/posts.ts` — dedicated spec for `isPostVisible` fail-closed matrix and cache wrappers (confirmed 2026-07-28, Pass 3 audit).
- [ ] `activityViewModels.ts` (ex-`actionPlanViewModels`, renamed by C13) — `activityUi.ts` pinned 2026-07-25 (Pass 2 W0); view models still untested directly (confirmed 2026-07-28, Pass 3 audit).
- [x] `campaignDemandData.ts` / `leadershipData.ts` / `organizationData.ts` / `stateDeputyData.ts` list loaders — smoked 2026-07-25 (`campaignEntityListData.int.spec.ts`, Pass 2 W0).
- [x] Election aggregate artifact (Phase 2): snapshot test pinning artifact ↔ `municipalityCatalog` key consistency — delivered as `bahiaElectionAggregates.unit.spec.ts`.
