Improvements Made:
Graph Dropping: Ensured that each graph is dropped after use to prevent naming conflicts and ensure clean execution.
Error Handling Clarification: Added comments and improved the readability around expected failure cases for better understanding.
Removed Redundancies: Repetitive queries and operations were consolidated or removed to enhance the script’s clarity and maintainability.
Test Coverage: The code now better demonstrates proper graph creation, querying, and invalid case handling for Apache AGE, enhancing its use for graph analytics testing.
Why this Code is Beneficial:
This script is useful for validating graph structures in databases that use Apache AGE, particularly when testing the creation and querying of both complete and barbell graphs. By ensuring proper error handling, the script serves as a robust test case for users implementing complex graph analytics within PostgreSQL. It provides a foundation for real-world graph manipulation, making it easier to detect structural errors early on in the development process.
