vite-plugin-testem

Vite plugin and Testem middleware helper for running browser tests with Testem. Currently at v1.0.1, released April 2026. Supports Vite 7/8 and Testem 3.20+. Key differentiators: provides both a Vite plugin to inject the Testem client script and a middleware helper to run Vite in middleware mode behind Testem, with automatic shutdown via on_exit hook. No alternative package directly bridges Vite and Testem.
