If the frame contains contentWindow, you can use frame.contentWindow.history.

But not all browsers support this property. If not, the frame's location should be stored in some variables. Bind event handler on your frame onload event like below(using jquery)

var frameHistory = [];
$(document).ready(function(){
    var frame = window.frames["test2"];
    $.bind(frame, "onload", function(){ //store location when frame loads
        frameHistory.push(frame.window.location.href);
    }
});

And in your button click event handler:

alert(frameHistory.length);
