Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Best open-source coding agent. SWE-bench performance is impressive and the architecture is well-designed.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Benchmark performance doesn't equal real-world reliability. Still needs human review for anything important.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Open-source coding agents will democratize software engineering productivity. SWE-Agent leads this movement.”
