Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“The best local development experience for edge functions. Miniflare emulates the entire Cloudflare platform locally.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Local emulation of D1, R2, KV, and Durable Objects means you develop at full speed without deploys.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Local-first development tools for edge platforms will become the standard. Wrangler leads this pattern.”
