"""
Django settings for running the backend test suite in isolation.

Always use this module instead of dispatcharr.settings when running tests:

    python manage.py test

`manage.py` selects this module automatically for the ``test`` command.

Django creates a separate empty database (``test_<POSTGRES_DB>``) and runs
migrations — your live data under /data/db is not used.

Why not dispatcharr.settings?
- Production/AIO points at the live ``dispatcharr`` database.
- django-db-geventpool breaks TestCase transaction isolation on pooled connections.

SQLite (``TEST_USE_SQLITE=1``) is an optional fallback for machines without
Postgres; production and CI should use the default Postgres test database.
