"""
Oracle Integration Tests for GoMag Import Manager
==================================================
Requires Oracle connectivity and valid .env configuration.

Usage:
    cd /mnt/e/proiecte/vending/gomag
    python api/test_integration.py

Note: Run from the project root so that relative paths in .env resolve correctly.
      The .env file is read from the api/ directory.
