Using dynamic variable values in tests?

@ed_truqc I was just looking at some code this morning that I worked on awhile ago and found a function I had that did this and is a bit more simple and hopefully less prone to errors.

//Generate UUID
function generateUUID() {
    var d = new Date().getTime();
    var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
        var r = (d + Math.random()*16)%16 | 0;
        d = Math.floor(d/16);
        return (c=='x' ? r : (r&0x3|0x8)).toString(16);
    });
    return uuid;
}

// Random number gen based on the time stamp
pm.environment.set("uuid", generateUUID());
console.log(pm.environment.get("uuid"));
