Description
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.…
