Added to Node.js in version 18.8, the node:test package is a framework for writing unit tests that has similarity with Mocha. Between the node:test and the already existing assert package, Node.js core contains a simple test framework.
This repository contains a few examples for using the node:test package.
To use the repository, simply clone it to your computer, and make sure Node.js 18.8 or later is installed. Everything required is baked into Node.js, and there is nothing to install.
