Node.js Test Runner: A Beginner's Guide

Historically, Node.js lacked an integrated test runner, which forced developers to rely on third-party frameworks such as Jest or Mocha.

This changed when James M. Snell proposed on GitHub that a test runner should be included within Node.js. The proposal developed over time and was eventually merged into the core of Node.js.

As a result, Node version 18 or higher includes a built-in test runner, which removes the need for external testing dependencies.

In this article, you will explore the features of the new test runner along with some examples.
