Testing Your JavaScript Applications

As people build increasingly more complex applications using JavaScript, the demands for testing those applications also increase. This has led to a wide variety of testing frameworks and tools specifically designed for JavaScript developers. Testing frameworks like QUnit, which is the test suite used by the jQuery project, have been around for some time and appear to have a broad user base. Other widely discussed tools include PhantomJS which is a headless WebKit that can be used for headless website testing in combination with a variety of other frameworks. If you are looking for a more complete list of testing tools, you can check the JavaScript frameworks list I maintain on my blog.

Despite the variety of testing options, many JavaScript developers have still not fully integrated unit testing or automated functional testing into their development process. This is part of the reason I was specifically interested in Dustin Butler’s recent ADC article on unit testing JavaScript applications with Jasmine. Jasmine is another popular solution for behavior driven development (BDD) which, as Dustin explains, is based upon the more common test driven development (TDD) approach but uses a natural language to define test based upon behaviors often described in an Agile user story.

I highly recommend reading Dustin’s article if you are interested in getting started testing your JavaScript applications or, even, if you are already doing testing using some other framework. As always, I welcome your feedback on the content we publish on the ADC – and if there are any other topics you would like to see covered, be sure to suggest them.
