testing mootools apps using rhino shell

As the guys form mozilla says “The JavaScript shell provides a simple way to run scripts in batch mode or an interactive environment for exploratory programming.”
So basically you can create some tests for you app based on javascript, without needing a browser, but using rhino.
With Mootools is a little complicated, as it needs a browser environment to run, and rhino does not provide this.
The solution for this is to simulate a browser.
A great work in this direction is made by John Resig, the guy behind jQuery, here.
Only that you will need to modify a little the script, to work with Mootools

add the following lines at the very end of the env.js script

var document = window.document;
window.Element = window.DOMElement;
window.navigator.platform = “MacPPC”;

window.navigator.platform can be any platform, I used this to reflect my platform.
