Description

Set up a comprehensive testing framework with unit tests, integration tests, and test automation to ensure code quality and reliability.

Tasks

Test Framework Setup

• Choose testing framework (Jest/Vitest/Node.js test runner)
• Configure test environment and TypeScript integration
• Set up test scripts in package.json
• Configure test coverage reporting

Unit Tests

• Test QR code generation service (src/service/qrcode.ts)
• Test parameter validation and error handling
• Test default option merging
• Test various QR code configurations

Integration Tests

• Test MCP server initialization
• Test tool registration and schema validation
• Test end-to-end QR code generation via MCP protocol
• Test error responses and edge cases

Test Infrastructure

• Set up test fixtures and mock data
• Create test utilities and helpers
• Configure test environment variables
• Add performance/load testing if needed

Acceptance Criteria

• Minimum 80% code coverage
• All core functionality tested
• Tests run automatically in CI/CD
• Clear test documentation and examples
• Fast test execution (< 30 seconds)

Priority

🟡 High - Essential for maintaining code quality

Dependencies

• Should be implemented after issues 🔧 [DAY 1] Update repository references from original fork to satwareAG #1 and 📦 [DAY 1] Update package.json with satwareAG organization metadata #2 are resolved
