Setup

var a = [];
    var doc = document;

Test runner

var xpathinput = doc.evaluate("//a[@class='test']", doc.documentElement, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);

var queryselectorinput = doc.querySelectorAll('a.test');

var arrNodes = doc.getElementsByTagName('a');
var tagnameinput = [];
for (var i = 0, l = arrNodes.length; i < l; i++) {
  if (arrNodes[i].getAttribute('class') == 'test') {
    tagnameinput.push(arrNodes[i]);
  }
}

var arrNodes = doc.getElementsByClassName('test');
var tagnameinput = [];
for (var i = 0, l = arrNodes.length; i < l; i++) {
  if (arrNodes[i].tagName == 'a') {
    tagnameinput.push(arrNodes[i]);
  }
}

var elems = $('a.test');

var arrNodes = doc.getElementsByClassName('test');
var i = arrNodes.length;
var tagnameinput = [];
while(i--){
  if (arrNodes[i].tagName === 'a') {
    tagnameinput.push(arrNodes[i]);
  }
}
