So I am a newbie in javascript and i had been going through some one else's code and I found this..

describe('deviceready', function() {

    it('should report that it fired', function() {

        spyOn(app, 'report');

        app.deviceready();

        expect(app.report).toHaveBeenCalledWith('deviceready');

    });

});

What I don't understand is:
What exactly does the describe keyword do?

info:

- Its a phonegap application

- We are using the spine.js and jQuery libraries
