Adds a `test` stage to the Dockerfile (prod deps + pytest + aiosqlite via the `dev` extras, never shipped) and a docker-compose.test.yml that runs it under its own Compose project name (`cassandra-test`). The project-name isolation matters because this host runs prod — a wrong `compose up` would otherwise recreate the live `app` container; namespaced project means the test container can't touch any prod container/network/volume. Tests use an in-memory aiosqlite DB (per tests/conftest.py) so the container has no MariaDB / Redis dependency and nothing on the prod DB is observed or mutated. Also adds aiosqlite to dev extras — tests have always implicitly needed it (the conftest pins DATABASE_URL to sqlite+aiosqlite:///:memory:); the declaration was just missing. Usage: docker compose -f docker-compose.test.yml run --rm test docker compose -f docker-compose.test.yml run --rm test pytest -k unsubscribe

# 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.
