bambuddy/backend/tests/integration/test_print_lifecycle.py

"""
Integration tests for the full print lifecycle.

These tests verify that:
1. Print start creates a new archive
2. Print complete updates archive status
3. Callbacks are properly executed
4. Energy tracking works
5. Notifications are sent

Note: These tests use mocking to avoid database conflicts.
Full end-to-end tests require the actual database setup.
