tess is a lightweight Node.js test runner that lets developers define simple test suites with an `it`‑style callback. By supplying a suite function (or an optional name and silent flag), it executes each test, logs results to the console (unless silenced), and returns an array of outcome objects containing the test title, function, success flag, and any error. It’s aimed at JavaScript developers who want a minimal, zero‑dependency alternative to larger testing frameworks.
