In-browser jasmine2 testing with requirejs

inBrowserTestingWithJasmine2.js

// You can paste this code into a browser console and it should work 
//  (provided preconditions below are met).

// Preconditions:
// 1. The page you load uses requirejs (so that window.require is defined).
// 2. A local server is running inside a folder with the correct dep's.
//    a. `mkdir bower_components && bower install jasmine`
// 3. Finally, run `python -m SimpleHTTPServer` to serve the directory


// Set up loading of the necessary libs from the local server using requirejs 
//  (assumed to be on the page).
