# Backend test strategy (Anexo24)

## Test suites

- `tests/e2e/`: full business flow (catalogs -> import -> export -> balances/discharges).
- `tests/integration/`: process API behavior and edge cases.
- `tests/unit/`: critical algorithms only (no trivial CRUD tests).

## Prerequisites

- PostgreSQL test database available.
- Environment variable:
  - `TEST_DATABASE_URL=postgresql://user:pass@host:5432/db_name`

## Run commands

- Fast subset (CI gate):
  - `pytest -q tests/unit tests/integration`
- Full suite:
  - `pytest -q tests`
  - `pytest tests -v -ra`
  - `pytest tests -v -ra -s`
- E2E only:
  - `pytest -q tests/e2e`

## CI recommendations

- Pull request gate:
  - Run unit + integration on every PR.
- Nightly / main branch:
  - Run full suite including E2E.
- Keep Celery eager mode for deterministic process endpoint tests:
  - `task_always_eager=True`
  - `task_eager_propagates=True`
