I don't own Sims 4, and might never, but I do know that how powerful testingcheatsenabled was for Sims 3 depended entirely on when it was entered. If you wanted it to be able to do all possible things, you had to put it in when on the main menu (before going into your own lot). If some people are getting the cheat to do things that others are not (which is what it sounded like to me from early in the thread) then try entering the cheat early. I would put money on such a cheat as the OP wanted existing, but it may take some hunting and diligent players searching for it. GOOD LUCK! :)
