QUnitX is a powerful testing library that brings the oldest, most mature, and flexible testing API in the JavaScript ecosystem to different JavaScript/TypeScript runtimes. With QUnitX, developers can run the same test file in Node.js, Deno, or in the browser using the default test runners.

One of the key features of QUnitX is its ability to run tests interchangeably in different runtimes. Whether you prefer the default test runner of Node.js or Deno, or a browser runner of your choice, QUnitX has got you covered. In the browser, you can even use the same browser test/filter UI of QUnit and share web links with your colleagues, thanks to the test filters through query params feature.

To get started with QUnitX, installation is simple. For Node.js and Deno, QUnitX is a zero-dependency test library that runs code in your target runtime's test runner. Please note that a default test runner is a new feature in Node.js v20.3+, so make sure you have the appropriate version. For browser installation, QUnitX mainly proxies to the QUnit API, allowing you to use the QUnitX CLI to get your browser tests to stdout/CI or use the watch mode during development.

QUnitX also offers concurrency options, allowing you to run tests in parallel or in series. You can even run them through the Node.js test runner's run() API. Additionally, QUnitX supports code coverage. When executed with Node.js, you can use any code coverage tool you like. However, when running tests in the browser mode, code coverage support is limited.

Overall, QUnitX provides developers with a universal testing solution for JavaScript and TypeScript. It offers flexibility, compatibility, and powerful features that make testing across different runtimes a breeze. Whether you're a Node.js enthusiast, a Deno advocate, or a browser testing aficionado, QUnitX has the tools you need to ensure the quality of your code.
