Reviewer scorecard
“One-line integration via proxy is genius. Change your base URL and instantly get logging, caching, and rate limiting.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“The proxy approach means minimal code changes. Cost tracking alone pays for itself when you have multiple models.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“As AI costs become a significant line item, observability and optimization tools like Helicone become essential.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
