About vitest

vitest
Vitest API and config reference (Jest-compatible)
vitest is an agent skill from the Supabase repository that serves as an API and configuration reference for Vitest, the testing framework powered by Vite. The skill describes Vitest as a Jest-compatible framework and covers mocking with vi.*, spies, fake timers, coverage configuration, fixtures, snapshots and test filtering. The reference notes that Vitest shares its config, transformers, resolvers and plugins with a Vite app. Its features include Vite-native transformation for fast test updates, a Jest-compatible API that makes most Jest suites a drop-in replacement, a smart watch mode that reruns only the tests affected through the module graph, native ESM, TypeScript and JSX support without extra configuration, multi-threaded workers for parallel test runs, and built-in coverage through V8 or Istanbul. The skill itself is based on Vitest 3.x. It is aimed at developers who write or migrate tests in a JavaScript or TypeScript project and want an agent that knows the Vitest API.
