intern

Intern. A next-generation code testing stack for JavaScript.

Intern is a complete test system for JavaScript designed to help you write and run consistent, high-quality test cases for your JavaScript libraries and applications. It can be used to test any JavaScript code. It can even be used to test non-JavaScript Web and mobile apps, and to run tests written for other test systems.

If you’re into name-dropping, Intern gets used every day by teams at Twitter, Stripe, Mozilla, IBM, Marriott, Philips, Zenput, Alfresco, Esri, HSBC, ING, Intuit, and more. It’s also the testing framework of choice for growing numbers of open-source projects.
