In their own words
Jest
Jest is a free, self-hosted JavaScript testing framework focused on checking correctness. It supports projects using Babel, TypeScript, Node, React, Angular, Vue and other technologies, and aims to run without configuration on most JavaScript projects. Snapshot tests compare rendered output with a saved reference. Tests run in separate processes for parallel execution, while the --coverage flag can collect coverage, including from files without tests. Mock functions and a custom import resolver support replacing objects and observing calls. Interactive watch mode reruns tests related to changed files. Installation guidance covers npm, Yarn, pnpm and Bun. Documentation describes webpack and Parcel use, but states that Vite is unsupported because of plugin-system incompatibilities. With Babel handling TypeScript, Jest transpiles tests without type-checking them during execution. A free plan is listed at free, with no paid plans or usage limits stated.
