  var scripts = 'array audio bugs css dates dom events features form function graphics json object script strings video';

  Benchmark.options.maxTime = 15;

  document.write(
    (
      '<script src="base/has.js"><\/script>' +
      scripts.replace(/\w+/g, '<script src="base/has/$&.js"><\/script>')
    ).replace(/base/g, base)
  );

  window.onload = function() {
    var bench = ui.benchmarks[0];
    has._testsCopy = Benchmark.extend({}, has._tests);
    bench.fn = has.all;
