Phase 1: Foundation and Core Unit Tests #147

Goal: Establish the testing infrastructure and cover the foundational building blocks of XMem.

Infrastructure Setup:

• Ensure pytest and pytest-asyncio are correctly configured in pyproject.toml.
• Create a tests/conftest.py for shared fixtures (e.g., event loop, basic mocks).
• Document the testing workflow in CONTRIBUTING.md.

Core Logic Testing:

• Implement unit tests for src/utils/*.py.
• Implement unit tests for data validation in src/schemas/*.py.
• Implement unit tests for database helper functions in src/database/*.py.

Basic Agent Tests:

• Implement unit tests for deterministic components of agents in src/agents/*.py.
