“Just make the Intern do the testing” Build Status

Intern is a complete test stack 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. Its functional testing capabilities can even be used to test non-JavaScript Web sites and apps, if you really want.

Features

  • 100% AMD, 100% Promises/A-based API
  • Instant one-off test execution in the browser or Node.js
  • Full statement, branch, function, and line code coverage reporting with Istanbul
  • Functional testing using the standard WebDriver API with a custom fluid, promises-wrapped interface based on WD.js
  • Integration with Sauce Labs for super simple continuous integration
  • Tested with Travis CI
  • Extensible interfaces (comes with TDD, BDD, and objects)
  • Extensible reporters (comes with basic console, WebDriver, and lcov reporters; tap planned)
  • Extensible assertions using the Chai Assertion Library (or any other assertion library that throws errors)

1: True events are not generated by JavaScript within the sandbox, so are able to accurately emulate how a user actually interacts with the application. Synthetic events generated by other test frameworks are limited by browser security restrictions.

2: Stand-alone means that unit tests can be executed in a browser by navigating to a URL without needing any special HTTP server or proxy for support.

3: Some older versions of QUnit can be used in conjunction with a 3rd party module to run on Node.js, but newer versions do not support Node.js and will break even with the use of 3rd party modules.

4: If it throws an error on failure, it works with Intern.

Quick start

  1. Install from npm

    cd /my/project/root
    npm install intern --save-dev
    
  2. Create a copy of the example configuration file in your package’s test directory and edit appropriately. See the configuration documentation for a list of all available options.

    mkdir tests ; cp node_modules/intern/tests/example.intern.js tests/intern.js
    
  3. Verify your configuration works by running the Node.js client and seeing that no errors are output.

    node node_modules/intern/client.js config=tests/intern
    
  4. Start writing tests! See the writing tests documentation to learn how.

Do you hate kittens and love old IE?

If you need to support IE 6–8, there is also a version of Intern for legacy browsers.
