+"""
+Pytest fixtures for the Schaeffler Automat backend test suite.
+
+The tests in this suite are divided into:
+  - Unit tests (no DB / network required):  excel_parser, models, schemas
+  - Integration tests (require running Postgres + Redis):  API endpoints, tasks
+
+Unit tests run offline; integration tests are gated by the 'integration'
+pytest mark so they can be skipped in CI without infrastructure.
