Jest is the most popular JavaScript testing framework with snapshot testing, mocking, and code coverage. Created by Meta. Being gradually replaced by Vitest in new projects.
Reviewer scorecard
“Component isolation done right. Independent versioning and testing per component is how design systems should work.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“The learning curve is steep and the tooling has rough edges. Storybook + npm packages achieve 80% of the value.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Component discovery and documentation are excellent. Designers can browse and understand available components easily.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
