Comprehensive testing strategies and quality assurance practices for design systems, components, and user interfaces.

🎯 Quality Focus

Testing ensures components work reliably across all user scenarios and technical environments.

  • • Functional correctness
  • • Visual consistency
  • • Performance standards

🔄 Test Types

A comprehensive testing strategy covers multiple layers from unit tests to end-to-end validation.

  • • Unit & integration tests
  • • Visual regression tests
  • • Accessibility audits

🚀 Automation

Automated testing enables rapid iteration while maintaining quality standards and catching regressions early.

  • • CI/CD integration
  • • Automated visual testing
  • • Performance monitoring

End-to-End Tests

Few, slow, expensive - but high confidence
