Intern
Intern is a free, open-source test system for JavaScript libraries and applications. It supports unit and functional testing, with tests written in JavaScript or TypeScript using TDD or BDD styles. Tests can run in Node.js, web browsers, or across multiple browsers and platforms through the Intern runner, with parallel execution and code coverage reporting. The project can target web pages and native or hybrid iOS and Android applications. For browser automation, it supports WebDriver-compatible tools and services, including Selenium, Appium, and Selendroid. Listed cloud options include Sauce Labs, BrowserStack, TestingBot, and a user’s own Selenium Grid. Continuous-integration integrations include Travis CI, Jenkins, and TeamCity. Intern’s extensible architecture allows custom test interfaces, executors, and reporters. It runs on Android, iOS, Linux, macOS, self-hosted environments, the web, and Windows. Installation is provided through npm, and the project uses the New BSD license.
