"make test" does create a list of symlinks to enable the CUPS backends like this:

ln -s $root/backend/http /tmp/cups-$user/bin/backend
ln -s $root/backend/ipp /tmp/cups-$user/bin/backend
ln -s $root/backend/lpd /tmp/cups-$user/bin/backend
[....]

It should create one for the snmp backend too, to allow testing its printer dicover capabilities:

ln -s $root/backend/snmp /tmp/cups-$user/bin/backend
