Comprehensive Installation Method Validation and Testing

🔍 Enhancement: Comprehensive Installation Method Validation and Testing

📋 Summary

Following the NPX compatibility fix in MR #6 (closed), we need comprehensive validation of all supported installation methods to ensure a consistent user experience across different setup approaches and environments.

🎯 Objectives

Universal Compatibility - Ensure all installation methods work across platforms
User Experience Consistency - Validate documented workflows match reality
Environment Robustness - Test across different Node.js versions and OS environments
Documentation Accuracy - Verify all README examples work correctly

🛠️ Implementation Tasks

Phase 1: Installation Method Inventory (1-2 hours)

NPX Direct: npx @haleyio/mcp-servers-gitlab
NPX with Flags: npx -y @haleyio/mcp-servers-gitlab
Global Install: npm install -g @haleyio/mcp-servers-gitlab && mcp-servers-gitlab
Local Install: npm install @haleyio/mcp-servers-gitlab && npx @haleyio/mcp-servers-gitlab
Source Build: git clone && npm install && npm run build && node dist/index.js
Docker: docker build && docker run

Phase 2: Environment Matrix Testing (3-4 hours)

Phase 3: Claude Code Integration Testing (2-3 hours)

Configuration Validation

{
  "gitlab": {
    "command": "npx",
    "args": ["@haleyio/mcp-servers-gitlab"],
    "env": {"GITLAB_PERSONAL_ACCESS_TOKEN": "token"}
  }
}

Alternative Configurations
- Node.js direct execution
- Global installation method
- Local path installation
Environment Variable Handling
- Token validation
- API URL configuration
- Error message clarity

Phase 4: Automated Validation Suite (2-3 hours)

Create installation validation script
Add environment detection logic
Implement success/failure reporting
Create troubleshooting recommendations

🧪 Technical Requirements

Validation Script Structure

#\!/bin/bash
# validate-installation.sh

echo "🔍 GitLab MCP Server Installation Validation"

# Test 1: NPX Direct
echo "Testing NPX direct installation..."
timeout 10s npx @haleyio/mcp-servers-gitlab --version || echo "❌ NPX direct failed"

# Test 2: Global Install
echo "Testing global installation..."
npm install -g @haleyio/mcp-servers-gitlab
timeout 10s mcp-servers-gitlab --version || echo "❌ Global install failed"

# Test 3: Environment Requirements
echo "Validating environment..."
node --version
npm --version
echo $GITLAB_PERSONAL_ACCESS_TOKEN | head -c 10

# Test 4: MCP Protocol Test
echo "Testing MCP protocol handshake..."
echo '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {...}}' | timeout 5s npx @haleyio/mcp-servers-gitlab
