  "dependencies": {
    "jquery": "~2.0.0"
  }
}

var googlecdn = require('google-cdn');

var bowerConfig = loadJSON('bower.json');
var markup = '<script src="bower_components/jquery/jquery.js"></script>';
googlecdn(markup, bowerConfig, {cdn: require('google-cdn-data')}, function (err, result) {
  if (err) {
    throw err;
  }

  assert.equal(result,
    '<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>');
});
