    <h1>Description</h1>
    <p>
      After hitting the button below, your device must vibrate for a short period of time (roughly one
      second). If it vibrates for a longer time (roughly five seconds, it should feel somewhat long) then
      the test has failed.
    </p>
    <button id='vib'>Vibrate!</button>
    <script src='/common/vendor-prefix.js' data-prefixed-objects='[{"ancestors":["navigator"], "name":"vibrate"}]'></script>
    <script>
      if (undefined !== navigator.vibrate) {
          document.getElementById("vib").onclick = function () {
              navigator.vibrate(5000);
              setTimeout(function () {
                  navigator.vibrate([]);
              }, 1000);
          };
      }
