#Testing

Stop bolting on a11y at the end—bake it into your design system with patterns that scale.

A stable testing stack that scales: unit tests with RTL, API mocks with MSW, and resilient E2E with Playwright.

Master TDD with real examples: writing tests first, making them pass, and refactoring for clean code.

Make accessibility a feature, not an afterthought: roles, ARIA patterns, keyboard UX, and test coverage with Testing Library.
