nodeunit‑watcher is a small command‑line utility that wraps the **nodeunit** test runner to add automatic, continuous testing. It watches the specified test files with `fs.watchFile` and re‑executes nodeunit each time a file changes, letting developers get instant feedback while they edit their tests. The tool is aimed at JavaScript/Node.js developers who already use nodeunit and want a simple “watch‑and‑run” workflow.
