ZProger 94782ee073 feat: add free-form tags on transactions
Third of the four ideas picked from the Maybe/Sure feature audit. Tags are
orthogonal to categories (category = what kind of spend, tag = which
event/project) — many-to-many, created inline while typing in the
transaction form, filterable from the Transactions page.

Also adds tests/test_backup.py, the first test coverage the backup
export/import path has ever had, and fixes a MissingGreenlet bug it
surfaced in restore_backup's tag-wiring.

Backend tests

Real integration tests against a real Postgres database — a dedicated aurum_test database created fresh, migrated, and dropped again on every run. They never touch the real aurum database or its data: the app's lifespan startup (which seeds against the real DB) is never triggered, and every route's DB dependency is overridden to point at aurum_test instead.

Running

The stack must already be up (docker compose up -d). Test dependencies aren't baked into the production image, so install them once per container lifetime, then run pytest inside the running backend container — it's the only place with network access to Postgres:

docker compose exec backend pip install -r requirements-dev.txt
docker compose exec backend pytest -v

Re-run just pytest -v for subsequent runs; the pip install only needs repeating after a container restart/rebuild.

Adding a test

  • Use the client fixture (an httpx.AsyncClient wired to the app) to hit the API the same way the frontend does — prefer this over reaching into services/models directly, so tests keep verifying the actual contract.
  • account_id and categories fixtures give you the same default account/categories a real fresh install seeds.
  • Every table is truncated and reseeded before each test (see conftest.py::_clean_database), so tests don't need to worry about leftover state or guess at IDs from a previous test.
