Try to run ad impressions in DFP with casperjs, doesn't work. Cool idea.

run-ad-impressions.js

var casper = require('casper').create(), url, count;
var system = require('system');

if (! casper.cli.has(0)){
    casper.echo('usage: run-ad-impressions.js <url> <number>');
}
url = casper.cli.get(0);
count = casper.cli.get(1);

casper.start(url);
casper.then(function() {
    runImpression(url, count);
});
casper.run();

function runImpression(url, count){
    casper.open(url).then(function(){
        casper.wait(3000, function(){
            system.stdout.write('.');
            if (count != 0){
                count = count - 1;
                casper.then(function() {
                    runImpression(url, count);
                });
            } else {
                system.stdout.writeLine('');
                casper.echo('ad impressions recorded. check dfp in ~30 minutes');
                casper.exit();
            }
        });
    });
}
