Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Remote caching and affected-only testing save enormous CI time. The project graph visualization is invaluable for large repos.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“If you have a monorepo with more than 5 projects, Nx pays for itself in CI time savings on day one.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Monorepos are winning. Nx and Turborepo are making them practical at any scale.”
