# The tests are new since the split out of cups-filters. Actually running them
# seems to be challenging. You need:
# - cups tools that are USE-optional
# - running avahi-daemon (as root!)
# - disable portage's pid-sandbox, which interferes with avahi
# - ipptool still fails to connect to port 8xxx
#
# If anything fails, a `while true` loop fails to successfully launch and break
# out of the loop, leading to a hang. Until there's an obvious recipe for
# successfully running the tests, restrict it.
