when pirates soft opened it was almost a week of suddenly letting a few people in to ride but not fully opened for anyone to walk in. once the walls come down and there is cast members watching the entrance then some type of opening is very close.
I don't think it's going to be quick testing, it looked like they replaced a section of track and a bridge to me and that is probably going to be extensively tested and possibly even the really slow going finger test or whatever it's officially called.
