Preparation code

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
var  interval,
     count = 0,
     scoped = {count:0};

function add(nb, string) {
  this.count+=nb;
}

function proxy(fn, context, args) {
  return function() { return fn.apply(context, Array.prototype.slice.call(arguments, 2));}
};
</script>
<script>
  Benchmark.prototype.teardown = function() {
    if(count > 0) {
      console.log("proxy isn't working as it should!");
    }
  };
</script>
