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.

  • Plain JavaScript code, in any module format (or no module format!)
  • Web pages generated by server-side languages (like Java, PHP, or Ruby)
  • Native or hybrid iOS, Android, and Firefox OS applications

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.

💡 If you’re an Intern user who’s new to Intern 4, see the [Changes from Intern 3](docs/changes_from_3.md) document for a summary of the major differences. For Intern 3 documentation, please see the Intern 3 README.

💡 Recently updated your browser and your WebDriver tests stopped working? You may need to [pin your WebDriver versions](./docs/running.md#selenium). <!-- prettier-ignore-end -->

Quick start

  1. Install from npm

    $ cd /my/project
    $ npm install intern
    
  2. Create an intern.json file in your project root.

    {
      "suites": "tests/unit/**/*.js"
    }
    
  3. Verify that your configuration works by running Intern and checking that no errors are output.

    $ ./node_modules/.bin/intern
    
  4. Start [writing tests](docs/writing_tests.md)!

TypeScript setup

Intern installs a global variable that tests may not be aware of if nothing imports the base intern package. To ensure Intern’s types are loaded, add the following to your tsconfig.json:

{
  "compilerOptions": {
    "types": ["intern"]
  }
}

Alternatively, add a triple-slash directive to the top of your suite files:

/// <reference types="intern" />

Compatibility

Intern can run unit tests in most browsers that support ECMAScript 5, including mobile browsers on Android and iOS, and in Node 6+. Note that Internet Explorer 9 is not supported.

Intern’s self-tests run against IE 10 and 11, Firefox 36 and current, Chrome 38 and current, and Safari 9 and 10, as well as the latest LTS and current versions of Node.

Intern can run functional tests using WebDriver-compatible applications and services, including Selenium, Appium, Selendroid. It has built-in support for cloud testing services from BrowserStack, CrossBrowserTesting, SauceLabs, and TestingBot.
