"""
Comprehensive Test Suite for GNN Processing Pipeline.

This module provides a complete testing framework with:
- Unit tests for all pipeline components
- Integration tests for end-to-end workflows  
- Performance tests for scalability validation
- Coverage analysis for code quality assurance
- Safe-to-fail implementations for graceful degradation

Test Categories:
- Fast: Quick validation tests (< 1s each)
- Standard: Integration and module tests (< 10s each)
- Slow: Complex scenarios and benchmarks (< 60s each)
- Performance: Resource usage and scalability tests

Architecture:
- Modular test organization by component
- Comprehensive fixtures and utilities
- Real implementations (no mocks)
- Performance regression testing
- MCP integration testing
- Pipeline orchestration testing
