🎯 Phase 3: Automated Testing Framework & Modern Development Infrastructure

[Victorcorcos]

Summary

This PR implements Phase 3 of the Parsec Web project, introducing a comprehensive automated testing framework and modern development infrastructure. The changes transform the project from manual testing to a professional, production-ready package with complete CI/CD integration.

🔬 Testing Framework Implementation

• Vitest Integration: Modern testing framework with ES6 modules support
• 13 Test Modules: Comprehensive coverage across all equation parser functionality
  • Unit Tests (8 modules): arithmetic, trigonometry, logarithms, strings, dates, complex, arrays
  • Integration Tests (2 modules): complex-expressions, mixed-types
  • Error Handling (3 modules): syntax-errors, runtime-errors, type-errors
• Performance Benchmarks: Speed regression detection with baseline metrics
• Coverage Reports: Automated test coverage tracking

🏗️ Development Infrastructure

• ESLint + Prettier: Code quality and formatting with automated fixes
• GitHub Actions: Automated CI/CD with multi-Node.js version testing
• WebAssembly Build Pipeline: Emscripten integration in CI environment
• Git Submodule Support: Automated equations-parser library integration
• npm Package Structure: Production-ready dual CommonJS/ES6 module exports

🚀 Key Technical Improvements

• Automated WASM Building: CI pipeline now builds WebAssembly from source
• Cross-Platform Testing: Node.js 18.x and 20.x compatibility verified
• Professional Package Structure: Ready for npm publishing with TypeScript definitions
• Modern Development Workflow: npm run style:fix, npm test, npm run dev commands

🔧 GitHub Actions Pipeline

The CI pipeline automatically:

1. Installs Emscripten in the CI environment
2. Initializes git submodules for equations-parser dependency
3. Builds WebAssembly module from C++ source
4. Verifies build artifacts exist before testing
5. Runs comprehensive test suite across multiple Node.js versions

This resolves the previous CI failures where equations_parser.js was missing.

🧪 Test Examples

# Run all tests
npm test

# Watch mode for development
npm run test:watch

# Coverage reports
npm run test:coverage

# Specific test categories
npm run test:unit
npm run test:integration

📊 Performance Impact

• Build Time: ~30 seconds (includes WebAssembly compilation)
• Test Execution: ~2-5 seconds for complete suite
• CI Pipeline: ~3-5 minutes end-to-end
• Zero Runtime Dependencies: Self-contained WebAssembly module

🎯 Benefits

• Professional Development: Modern tooling and automated quality checks
• Regression Prevention: Comprehensive test coverage prevents breaking changes
• Cross-Platform Ready: Verified compatibility across environments
• Production Ready: Professional package structure for npm publishing
• Maintainability: Clear code standards with automated enforcement

This PR establishes the foundation for reliable, scalable development of the Parsec Web library with enterprise-grade testing and development practices.

@niltonvasques I'll merge this PR to test the parsec_flutter properly (oxeanbits/parsec_flutter#28)

You can still review it as you wish and I'll make changes by opening a new PR
