Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Non-negotiable for any serious component library. Visual testing, docs, and interaction testing in one place.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Setup can be painful and builds are slow, but the alternative — no component isolation — is worse.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“The best way to browse and understand a design system. Addons for accessibility and responsive testing are invaluable.”
