Attio Simple MCP Server

# Unit Tests Fast, isolated tests with mocked dependencies. **Characteristics:** - Execution time: <5 seconds total - Dependencies: All external APIs mocked - Run in: CI/CD pipeline - Coverage target: 80% of critical components **Structure:** - `tools/` - Tests for individual MCP tools (create-company, search-people, etc.) - `utils/` - Tests for utility functions (error handling, validation) - `lib/` - Tests for library code (schema cache, helpers) **Running:** ```bash npm run test:unit # Run all unit tests npm run test:watch # Watch mode for development npm run test:coverage # Run with coverage report ``` **Writing Unit Tests:** - Use MockAttioClient from `tests/helpers/mock-attio-client.ts` - Use fixtures from `tests/fixtures/` for test data - Focus on business logic, not API communication - Test edge cases and error conditions
