JUnit Viewer is a lightweight Node‑based tool that parses JUnit‑style XML test reports (from a single file or an entire directory tree) and presents them as a searchable, single‑page HTML view, optionally serving the results via an Express server or saving them to a file. It targets developers and CI pipelines that need a quick, framework‑agnostic way to visualise test outcomes without extra dependencies. (The project is now deprecated in favor of xunit‑viewer.)
