Calling / Inserting functions before jQuery document.ready

Question

// this is a unit testing file, JsTestDriver style
TestFunction.prototype.testFunction = function() {
    // calls my function

    var result = realReady.apply(this, arguments);
    console.log("After ready.");
    return result;
};
