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
“Free tier with no restrictions is remarkable. Completion quality rivals Copilot for most languages.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Hard to argue with free. The enterprise features and Windsurf IDE show they have a real business model beyond the free tier.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Giving away code completion to win IDE market share with Windsurf is a smart long-term play.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
