Common Questions

What are the best JavaScript unit testing tools?

Pros

Pro
Tests run in the order they're added to the suite

Pro
Works really well if performing DOM Testing

All frontend developers already know the ease that jQuery framework has brought to their lives, in handling DOM events and accessing elements. Since Qunit was built as a part of jquery (is even used by jQuery itself for unit testing) hence it makes testing of DOM elements a lot easier.

Pro
Extremely easy to start from scratch

Seriously! All you have to do is include the Qunit library from the CDN, then create your Testcases js file, and RUN IT! . Your outputs would be displayed in a pretty little format in your browser.

Pro
Supports deferring tests

No need to comment out your entire test case, now that you have Buster, which supports deferring a test so it doesn't actually run, but you get notified that there’s a deferred tests every time you run your test suite.

Pro
Flexible; extend it to wrap other test-frameworks

Have your test cases written in another framework, want to use BusterJS to run the tests, then you're in luck. BusterJS can be easily wrapped around other test frameworks. If you need to know how to do it, here's a link that showing just that.

Pro
Has support for NodeJS testing.

Working on a NodeJS app? BusterJS can help you Unit test it. This pretty much works just like browser tests, but you need to require Buster.JS in your tests.

Pro
You have the option of either running tests headless or via the browser

Don't have time to go through the lengthy process of opening up your browsers? BusterJS gives you the option of performing Headless tests. These are powered by PhantomJS; hence all your testing is done within the command line.

Cons

Con
Testing of Async operations can be a little tough at times.

Qunit, expects us to call the start() function before the Async function itself, and stop() after it stops. This can be a problem when you have no way of knowing, when your function will start or stop (your testing a number of dependent functions)

Con
Has no plugins for major IDE's (Eclipse/IntelliJ) yet.

Do you prefer running your test cases from inside your IDE? well BusterJS will make that a lot difficult for you if not impossible. You'll have to run Buster using the good old way of spawning up a new terminal for running the tests.
