The RuneScape Testing Beta is the version of RuneScape that Jagex add extra features to and then swap with the current version of RuneScape. On 4th August 2009 Jagex invited people who hadn't played before into Jagex to play on the Runescape Testing Beta. They didn't see anything new, Jagex just invited them to see the reaction of new players towards the game. It is unknown whether Stellar Dawn will have a testing beta but FunOrb probably doesn't as it isn't one big game it is multiple games. If it does it would have one for each game. It is possible that Jagex make a testing beta when they decide on a definite update however it is unknown.
