yes, it is definitely possible to test with QUnit. Actually all our internal DEV tests are relying on QUnit.

on your page, you need to add a reference to the QUnit javascript, then you need to add some markup which has the QUnit CSS classes applied - qunit will use those classes to find the elements where it will inject the test results, something like this:

<div style="float:right;width:400px;overflow:auto;">     

    <h1 id="qunit-header">Test results</h1>     

    <h2 id="qunit-banner"></h2>     

    <h2 id="qunit-userAgent"></h2>     

     <ol id="qunit-tests"></ol>

</div>

then you can start testing :

$(window).load(function () {         

    QUnit.init();     

    QUnit.start();     

    module("igCombo");

    test("mycombotest1", function() {      

        var comboChild = $('#combo1').find('.someClass);      

        equals(...); // use the QUnit API here

    }

}

Hope it helps. Thanks,
