Debugging Google Analitycs tracking codes

All the sites that I work on, have google analitycs tracking code, but how can I debug them to see if it's working?

I used to put a "console.log" line below the tracking code:

__ga.push(["trackEvent","category","event","label"]);
console.log("tracking is working");

But I figured out a better way to do this. If I am working on development or test environment, I override the "__ga.push" method. Something like this:

var _gaq = _gaq || []; 
var _url = window.location.href.toString();
var _regex = /(development|test)/g;

(function()
{
    //Environment is Development or Test
    if(_regex.test(_url))
    {
        window._gaq.push = function(array)
        {
            console.log(array.join(" : "));
        }
    }
    else
    {
         _gaq.push(['_setAccount', 'UA-36379912-1']);
         _gaq.push(['_trackPageview']);
        (function() {
            var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
            ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
            var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
        })();
    }
})();
