This is my test file which does execute but after grunt has ended so the servers closed so it fails.

casper.test.begin('Testing index', function suite(test) {
    require('./modules/include.js')(test);

    casper.start(url + 'index.html', function(){
        test.assertHttpStatus(200);
    });

    casper.then(function() {
        checkAllResourcesFound();
    });

    casper.run(function () {
        test.done();
    });
});
