"""
Comprehensive Neo4j-Qdrant Integration Test Suite
This test suite validates the complete Neo4j-Qdrant integration workflow with focus on:
1. MCP tool context wrappers (extract_and_index_repository_code, smart_code_search, etc.)
2. Code extraction from Neo4j repositories with proper validation
3. Code indexing in Qdrant with embeddings and metadata
4. Validated search functionality combining both systems
5. Enhanced hallucination detection with dual validation
6. Performance requirements and error handling
Test Structure:
- Mock components properly to isolate integration points
- Include both success and failure scenarios
- Validate performance requirements (<2s for searches)
- Clear test documentation and assertions
