How to start implement QUnit

How to start implement QUnit

Hi everyone, 
I am new in the QUNit world and Im not English so apologise for any future mistakes XD
So my issue is:
I have an HTML page where I load a MediaPlayer.swf.
I'll post how my folders are organized:

MediaPlayer (folder)
 - app  (folder)
      -- img  (folder)
      -- js  (folder)
            --- main.js
            --- jquery.js
            --- backbone.js
            --- handlebar.js
            --- qunit.js
      -- styles  (folder)
 - MediaPlayer.html
 - MediaPlayer.swf

so now what Im wondering is:
I want to test functions, views, etc that are in main.js and of course I dont want my test results to be showed in MediaPlayer.html but I would like to create a test.html page where I need to attach all my project and from there run my tests. I have not  quite understood how to implement all this, where shall I start from? and then How do I run those test when I want? Because for the moment what I have managed to do is testing my function in MedaPlayer.html and straight away once launched the page.
Thank youuuu
