What

jsUnity is a lightweight JavaScript unit testing framework that is context-agnostic. It doesn't rely on any browser capabilities and therefore can be run inside HTML, ASP, WSH or any other context that uses JavaScript/JScript/ECMAScript.

Why

There are already several unit testing frameworks for JavaScript that are browser-centric. jsUnity aims to just focus on JavaScript as a language that's used beyond the browser context. jsUnity can be used in server-side JavaScript implementations.
