Intern is minimally prescriptive and enforces only a basic set of best practices designed to ensure your tests stay maintainable over time. Its extensible architecture allows you to write custom test interfaces, executors, and reporters to influence how your tests run & easily integrate with your existing coding environment. Intern also comes with Grunt tasks so it can be quickly added to existing Grunt-based workflows, and is designed to work out-of-the-box with popular continuous integration services like Jenkins and Travis CI.
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.
