Reviewer scorecard
“Issue-to-PR workflow is the right abstraction. The planning step prevents the 'just generate code' antipattern.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Still limited in what it can handle. Works for straightforward issues but struggles with anything architecturally complex.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“This is where all development is heading — describe what you want, AI plans and implements. GitHub has distribution advantage.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
