Christ went to the wailing place, Paradise, to gather all those from the Old Testament that would enter heaven after him.
I’ve never believed that he was tested there. He was God, He had risen from the dead. Why would he be tested?
“Why would he be tested?”
I have wondered the same thing about “Why have you forsaken me.”
My insufficiently humble opinion, not backed AFAIK by the Catholic Church, is that one of His objectives was to experience everything that man can experience—except sin, of course.
