"""
End-to-End Tests for SEREACT API

These tests cover the complete user workflows described in the README:
1. Use pre-seeded API key for authentication
2. Team creation and management
3. User management within teams
4. API key authentication
5. Image upload and storage
6. Image search and retrieval
7. Multi-team isolation
8. Advanced search functionality
9. Image collections management
10. User role and permission testing
11. Image metadata operations
12. Real database integration

These tests are completely self-contained:
- Use pre-seeded test data (API key, team, admin user)
- Run all tests against this test data
- Clean up created test data at the end

Run with: pytest tests/test_e2e.py -v
For integration tests: pytest tests/test_e2e.py -v -m integration
For real database tests: pytest tests/test_e2e.py -v -m realdb
