Intern is a complete open source 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.

This presentation showcases the latest advances in JavaScript testing and introduces you to The Intern, the test runner of choice in projects at companies including SitePen, Mozilla and Stripe. It enables testing of any JavaScript code and works well with Travis CI, Sauce Labs, and other tools. The talk will include several examples, starting from basic jQuery sites to large modular web applications.
