Is there a way to test an arena squad without fighting in arena?

I farmed up 501st, anakin and Shaak ti to use in the arena, but I don’t know if they are ready yet. I’m afraid to test them out in arena and get knocked back if they aren’t ready. What’s the best way to test their strength, or do I just have to bite the bullet and get knocked back a bit if they aren’t ready?
