Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Too expensive for what it offers. Plenty of open-source alternatives.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Solid execution. Does what it promises and the DX is clean.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Interesting concept but the execution isn't there yet. Give it 6 months.”
