# Testing

## Web (`apps/web`)

- Unit: `src/tests/unit/` with Vitest + Testing Library
- Integration: `src/tests/integration/`
- Mirror setup in `src/tests/setup.ts`

## API (`apps/api`)

- Unit: `tests/unit/` — mock providers via interfaces
- Integration: `tests/integration/` — mark with `@pytest.mark.integration`
- Use `tests/conftest.py` fixtures

## General

- Test changed behavior, not implementation trivia.
- Parser/normalization/trends/safety filters require tests when touched.
- Contract tests when OpenAPI or shared schemas change.
