The pragmatic front-end tester
summary
Claims that front-end testing can be simple, demonstrates a tiny counter component, and shows a real test that renders the component, queries it with getByText, fires a click event, and asserts the DOM update. Advocates using DOM Testing Library to avoid implementation-detail coupling that creates a brittle “third” consumer, reducing false positives and keeping tests framework-agnostic. Shows that tests run fast, mirror user interactions, and actually catch regressions without breaking for internal refactors.
