# Ad-hoc test runner.
#
# STANDALONE — do not combine with docker-compose.yml. The `name:` field
# below puts the test container in its own Compose project (`cassandra-test`)
# so it CANNOT collide with the live prod stack on this host (containers,
# networks, volumes are all namespaced by project).
#
# Usage:
# # Run the full suite:
# docker compose -f docker-compose.test.yml run --rm test
#
# # Run a specific file or test:
# docker compose -f docker-compose.test.yml run --rm test pytest tests/test_email_digest_job.py -v
# docker compose -f docker-compose.test.yml run --rm test pytest -k unsubscribe
#
# # Open a shell in the test image (e.g. to poke around with pytest --pdb):
# docker compose -f docker-compose.test.yml run --rm test bash
#
# # Rebuild after a pyproject.toml change:
# docker compose -f docker-compose.test.yml build test
#
# Tests use an in-memory aiosqlite DB (see tests/conftest.py), so there is
# no MariaDB / Redis dependency and nothing touches the prod database.

# Same volume mounts as the dev override — edits on the host take effect
# on the next `run` without rebuilding the image.
volumes:

- ./tests:/app/tests
- ./alembic:/app/alembic
- ./alembic.ini:/app/alembic.ini:ro

environment:
# Sentinels so app.config can be imported without a real .env / DB.
# tests/conftest.py also sets these defensively.
