✅ **Environment Filtering**: Tests `ENABLED_TOOLS` functionality ### Test Data - **Mock API Token**: `test-token-123` - **Test Base URL**: `https://webexapis.com/v1` - **Mock Responses**: Configurable per test case ## Test Categories ### 🔧 Unit Tests - Configuration module functions - Individual tool implementations - Utility functions - Error handling ### 🔗 Integration Tests - Tool discovery system - MCP server integration (MCP 2025-06-18) - API request construction - Authentication flows - Transport mode testing (STDIO and HTTP) ### 🎯 End-to-End Tests - Complete workflow validation - CLI interface testing - Performance verification - Concurrent execution ### 🚨 Error Handling Tests - Network failures - API errors (401, 404, 500) - Malformed responses - Missing configuration ## Mock Strategy ### API Mocking Tests use a sophisticated mocking strategy: ```javascript // Configurable mock responses global.fetch = async (url, options) => { // Capture request details for verification capturedUrl = url; capturedOptions = options; // Return controlled response return { ok: true, status: 200, json: async () => ({ success: true }) }; }; ``` ### Environment Isolation Each test suite manages its own environment: ```javascript beforeEach(() => { originalEnv = { ...process.env }; process.env.WEBEX_PUBLIC_WORKSPACE_API_KEY = 'test-token'; }); afterEach(() => { process.env = originalEnv; }); ``` ## Coverage Areas ### ✅ Fully Covered - Configuration management - Tool discovery - API request construction - Authentication handling - Error scenarios - CLI functionality ### 📈 Metrics - **Function Coverage**: 100% of exported functions -

Commit proceeding... ``` ### 📋 Setup Instructions Pre-commit hooks are automatically installed when you run: ```bash npm install ``` To manually set up or reinstall: ```bash npm install husky --save-dev npx husky init ``` ## HTTP Mode Testing ### Testing HTTP Transport The test suite includes comprehensive testing for the new HTTP transport mode: ```bash # Test HTTP mode functionality npm run start:http & SERVER_PID=$! # Test health endpoint curl http://localhost:3001/health # Test MCP initialization curl -X POST http://localhost:3001/mcp \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2025-06-18", "capabilities": {}, "clientInfo": {"name": "test", "version": "1.0.0"}}}' # Clean up kill $SERVER_PID ``` ### MCP 2025-06-18 Protocol Testing - **Session Management**: Tests proper `mcp-session-id` header handling - **CORS Configuration**: Validates `exposedHeaders` configuration - **StreamableHTTP Transport**: Tests SSE response format - **Protocol Compliance**: Ensures MCP 2025-06-18 compatibility ## Continuous Integration Tests are designed to run in CI/CD environments: - No external dependencies - Deterministic results - Fast execution (< 15 seconds) - Clear failure reporting - Pre-commit hooks for local quality assurance - MCP protocol compliance validation ## Contributing When adding new features: 1. **Add corresponding tests** for new functionality 2. **Update existing tests** if behavior changes 3. **Maintain 100% pass rate** before submitting 4. **Follow naming conventions** for test descriptions 5. **Include error scenarios** in test coverage ### Test Naming Convention ```javascript describe('Component Name', () => { describe('method/feature name', () => { it('should describe expected behavior', () => { // Test implementation }); }); }); ``` ## Debugging Tests ### Common Issues - **Environment variables**: Ensure test environment is isolated - **Async operations**: Use proper async/await patterns - **Mock cleanup**: Restore original functions in afterEach - **Timing issues**: Use deterministic delays in tests ### Debug Commands ```bash # Run specific test file node --test tests/webex-config.test.js # Run with verbose output node --test --test-reporter=spec tests/*.test.js # Debug specific test node --inspect-brk --test tests/specific.test.js ``` This comprehensive test suite ensures the reliability and maintainability of the Webex MCP Server codebase.
