I've never had it on the Airbus, but on the 737 it was quite common to get a request from maintenance to perform an autoland to get the system back to full usable status again. Usually after some maintenance action. In that case an autoland had to be done at the earliest convenient time, not because we pilots needed it, but because the aircraft did. If the autoland was successful and fully within specs, and it always was, the autoland system was allowed to work in real required autoland conditions.
Pilots do have recency requirements as well, but those are usually taken care of during the regular simulator training.
