Integration/API tests need a real PostgreSQL instance (JSONB, trigram/FTS
|
||
|
|
indexes, and native enums are Postgres-specific — see docs/database.md) and
|
||
|
|
Redis. Point `TEST_DATABASE_URL` / `TEST_REDIS_URL` at throwaway instances,
|
||
|
|
e.g. via `docker compose up -d postgres redis` and a separate test database:
|
||
|
|
|
||
|
|
createdb -h localhost -U aurora aurora_core_test
|
||
|
|
|
||
|
|
Unit tests (tests/unit/) never touch either and always run offline.
