- Replace PostgreSQL AsyncPostgresSaver with MemorySaver in test fixtures
- Create test_app fixture with test_lifespan using in-memory dependencies
- Mock LLM model to avoid requiring API keys during tests
- Update test_api.py to use test_app fixture instead of production app
- Fix test_root endpoint URL to match root_path configuration
- All API tests now pass without requiring external services (0.06s vs 30s+ timeout)
This change allows tests to run in isolation without PostgreSQL or API keys,
making them faster and more reliable for CI/CD and local development.
- Add `_extract_mcp_content_text()` helper in naliia_tools.py to safely
extract text from MCP results, preventing IndexError on empty content
- Replace all direct `result.content[0].text` accesses with safe helper
- Improve customer identification with preservation of existing state
- Add proper JSON parsing with fallback and error handling
- Simplify webhook state management (use agent's checkpointer internally)
- Update system prompt to remove check_mcp_connection tool reference
- Fix tests to use async mocks and correct expected values
