"""
Comprehensive Core Module Tests

This module provides thorough testing for all core GNN processing modules
to ensure 100% functionality and coverage. Each test validates:

1. Module import capabilities and dependency resolution
2. Core functionality and data processing
3. Error handling and edge cases
4. Integration with other modules
5. Performance characteristics
6. Documentation and API consistency

All tests execute real methods and file operations without mocking; tests may skip if optional backends are unavailable.
