feat: implement Phase 1 Vitest test infrastructure

[brownjer3]

Summary

This PR implements Phase 1 of the comprehensive Vitest test infrastructure for the Pipe MCP Server. It establishes a robust, scalable testing foundation that enables efficient test development and ensures high code quality.

What's Included

🧪 Core Test Infrastructure

• Vitest Configuration: Full TypeScript support with workspace configuration
• Test Directory Structure: Organized fixtures, mocks, utilities, and test environments
• Custom Matchers: Domain-specific assertions for JWT, UUID, and MCP messages
• Test Factories: Consistent data generation for users, teams, sessions, and MCP messages

🔧 Test Utilities & Fixtures

• Auth Fixtures: Complete authentication context creation and JWT token generation
• Database Fixtures: Mocked Prisma, Redis, and Neo4j clients with test data seeding
• MCP Protocol Fixtures: Mock MCP handlers and message builders
• WebSocket Fixtures: Mock Socket.io server and client for real-time testing

🎯 Mock Modules

• Redis Mock: In-memory Redis implementation for testing
• Prisma Mock: Complete database client mock with error handling
• Neo4j Mock: Graph database driver mock with session support

📊 Test Coverage

• 116 Tests Passing: All test cases run successfully
• Example Unit Tests: Comprehensive tests for encryption and logger utilities
• Enhanced Scripts: Multiple test commands for different scenarios

Key Features

• Zero-Configuration: Tests work out of the box with TypeScript support
• Scalable Architecture: Modular structure supports easy test addition
• Performance Optimized: Thread pool configuration for fast execution
• CI/CD Ready: Configured for both local development and CI environments
• Developer Experience: Custom matchers and utilities reduce boilerplate

Test Commands

npm test              # Run tests in watch mode
npm run test:run      # Single test run
npm run test:coverage # Run with coverage report
npm run test:ui       # Open Vitest UI
npm run test:unit     # Run unit tests only

Files Changed

• 30 files added with 3,140 lines of test infrastructure
• Core configs: vitest.config.ts, test environment setup
• Test utilities: Custom matchers, factories, helpers
• Mock modules: Redis, Prisma, Neo4j automatic mocks
• Example tests: Encryption and logger service tests
• Documentation: Implementation plan and Phase 1 summary

Next Steps

This foundation is ready for Phase 2 implementation, which will include:

• Comprehensive unit tests for all core components
• Integration tests for API endpoints and database operations
• End-to-end tests for complete user workflows
• Performance benchmarks and load testing

Test Results

✅ All 116 tests passing
✅ Zero test failures
✅ Ready for Phase 2 development

Documentation Update for Phase 1 Vitest Test Infrastructure ✅

I've successfully updated the documentation in /docs to properly reflect the new test infrastructure.

Todo List:

• Review existing /docs directory structure
• Examine newly added test documentation files
• Check main project documentation for needed updates
• Update documentation to properly reference new test infrastructure
• Ensure documentation consistency and completeness
• Run linting/formatting if available
• Commit and push changes

Updates Made:

1. docs/README.md - Added Testing Guide to documentation structure and quick links
2. docs/development.md - Enhanced testing section with comprehensive Vitest infrastructure details
3. README.md - Updated development commands to highlight comprehensive testing capabilities

Key Documentation Enhancements:

• Navigation: Added link to comprehensive testing guide in main docs index
• Test Commands: Documented all new test commands (test:ui, test:coverage, test:unit, etc.)
• Infrastructure: Documented custom matchers, fixtures, and mock infrastructure
• Structure: Updated project structure to include test infrastructure
• Quick Access: Added testing information to documentation navigation

Files Updated:

• docs/README.md - Added testing guide to documentation structure
• docs/development.md - Enhanced testing section with Vitest details
• README.md - Updated development commands for testing

The documentation now properly reflects the robust testing foundation that Phase 1 implemented, making it easy for developers to understand and use the comprehensive test infrastructure!
