Loading Screen Testing?

I was wondering if there was any way to test out a Loading Screens functionality when it comes to grabbing the map name and so forth, without having to join a server over and over?

www.example.com/loadingscreen/?steamid=yoursteamid&mapname=yourmapname



$steamid = $_GET['steamid'];
$mapname = $_GET['mapname'];


Thank-you very much! :downs:
