This is a pretty minor one, but it's not covered in the documentation. If you have a jasmine spyOn call inside of the describe but outside of a test or outside of a beforeEachit will not run!
Have you ever wanted to just check out someone's Jasmine unit test's without having to set up an environment? Or maybe you wanted a quick and easy space to write and run some of your own tests.
Unit Testing in javascript is usually pretty straightforward. You pick a framework like Jasmine or QUnit, you write some tests, and you run them in your browser or in something headless like PhantomJS.
