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 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.
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 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.
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.
Con Currently still in Beta; some of the stuff still has bugs
