some tricky test moments in Jasmine

If you know RSpec, Jasmine is easy! But some common uses of JavaScript may not be as immediately obvious.

Try to use Jasmine (you could use your own setup or just tryjasmine.com) to write some specs that cover cases like these. The links will load up an example.

• jQuery DOM manipulation - change the DOM based on state of the DOM
• jQuery event binding - verify an event was bound
• [More jQuery event binding(http://tryjasmine.com/?gist=1378942) - example from Chris Powers
• conditional stubbing w/ backbone - an object that's isolated from its depended-on backbone model

//http://www.plupload.com/examples/core

// Esto debe ir en el html para poder acceder a los helpers de rails
App.pluploadConfig = {
  url: "https://neufert-tmp-cdn.archdaily.net.s3.amazonaws.com/",
  /* try replacing file_name_name: false by send_file_name: false
   if dont work then modify plupload with:
