Cross-platform MCP server with comprehensive testing and deployment infrastructure. ### Test Results Status - ✅ **Windows Testing**: Node.js 18 & 20 - PASSING - ✅ **macOS Testing**: Node.js 18 & 20 - PASSING - ✅ **Linux Testing**: Node.js 18 & 20 - PASSING - ✅ **Docker Build & Test**: Container builds and runs correctly - PASSING - ✅ **Security Audit**: No vulnerabilities detected - PASSING - ❌ **Deploy**: GitHub Container Registry permissions issue (non-critical) ## 🧪 Testing Infrastructure ### Test Framework Setup - **Framework**: Jest with TypeScript and ESM support - **Configuration**: `jest.config.js` with proper ESM handling - **Setup File**: `jest.setup.mjs` for environment configuration - **Test Scripts**: - `npm test` - Run all tests - `npm run test:coverage` - Run with coverage reports - `npm run test:watch` - Development mode with auto-reload - `npm run test:ci` - CI-friendly test execution ### Test Files Created ``` __tests__/ ├── basic.test.ts # Cross-platform compatibility tests test-personas/ ├── test-persona.md # Valid test persona for testing ├── invalid-persona.md # Invalid persona for error handling tests ``` ### Test Coverage Areas 1. **Package Configuration Validation** - Correct package.json structure - Required dependencies present - Binary paths configured correctly 2. **File System Structure** - Required directories exist - Persona files are readable - Build artifacts are correct 3. **Cross-Platform Compatibility** - Windows path handling (`C:\Users\...`) - Unix path handling (`/home/user/...`) - Relative path resolution - Path normalization across platforms 4. **Environment Variables** - `PERSONAS_DIR` configuration - `NODE_ENV` handling - Production vs development modes 5. **Build Process Validation** - TypeScript compilation success - Output file generation - Distribution directory structure ## 🐳 Docker Implementation ### Multi-Stage Dockerfile ```dockerfile # Builder stage - installs all dependencies and builds FROM node:18-alpine AS builder # ... build process ... # Production stage - optimized runtime image FROM node:18-alpine AS production # ... production setup with non-root user ... ``` ### Docker Features Implemented - **Multi-stage builds** for optimized production images - **Non-root user** (`persona:nodejs`) for security - **Health checks** for monitoring - **Volume mounting** for custom personas - **Environment configuration** via ENV variables - **Security hardening** with minimal attack surface ### Docker Compose Setup - **Production service**: Optimized for deployment - **Development service**: Hot-reload for development - **Resource limits**: Memory and CPU constraints - **Health monitoring**: Automated health checks ### Docker Files Created ``` Dockerfile # Multi-stage production build docker-compose.yml # Orchestration for prod/dev .dockerignore # Optimized build context ``` ## 🚀 GitHub Actions CI/CD Pipeline ### Workflow Structure (`.github/workflows/ci.yml`) #### 1. **Cross-Platform Testing Matrix** ```yaml strategy: matrix: os: [ubuntu-latest, windows-latest, macos-latest] node-version: ['18', '20'] ``` #### 2. **Security Audit Job** - **npm audit** for vulnerability scanning - **Snyk security scan** (optional with token) - **Dependency validation** #### 3. **Docker Build & Test Job** - **Docker Buildx** setup for advanced features - **Image building** with GitHub Actions cache - **Container testing** to verify functionality - **Cache optimization** for faster builds #### 4. **Deploy Job** (Deployment Pipeline) - **Container registry** authentication (ghcr.io) - **Multi-tag strategy**: branch, SHA, semver - **Image pushing** to GitHub Container Registry - **NPM publishing** on releases ### CI/CD Features Implemented - **Parallel execution** across all platforms - **GitHub Actions cache** for faster builds - **Automated dependency caching** - **Security scanning integration** - **Artifact generation** and storage - **Release automation** with changelog generation ## 🔧 Issues Resolved ### Problem 1: Jest ESM Configuration **Issue**: Jest couldn't handle ES modules and TypeScript together **Solution**: - Used `ts-jest/presets/default-esm` preset - Added `extensionsToTreatAsEsm: ['.ts']` - Configured proper module name mapping - Created `.mjs` setup file for ESM compatibility ### Problem 2: Docker Image Loading in CI **Issue**: Built Docker image wasn't available for testing in GitHub Actions **Solution**: Added `load: true` to `docker/build-push-action` configuration ### Problem 3: Docker Cache Export Issues **Issue**: Default Docker driver doesn't support GitHub Actions cache **Solution**: Set up Docker Buildx with container driver for cache support ### Problem 4: Container Registry Permissions **Issue**: `denied: installation not allowed to Create organization package` **Status**: Known limitation - requires GitHub repository package permissions **Impact**: Non-critical - doesn't affect core functionality ## 📁 File Structure Added ``` persona-mcp-server/ ├── __tests__/ │ └── basic.test.ts ├── test-personas/ │ ├── test-persona.md │ └── invalid-persona.md ├── .github/ │ └── workflows/ │ └── ci.yml ├── jest.config.js ├── jest.setup.mjs ├── Dockerfile ├── docker-compose.yml ├── .dockerignore ├── install.ps1 └── TESTING_AND_DEPLOYMENT.md (this file) ``` ## 🎯 Cross-Platform Installation ### Windows Installation **PowerShell Script**: `install.ps1` -
