You can use a loop, here is hack(ish) function that perhaps work (ie not
tested too much)

 testfile () {
    local OPTIND=1 f=${!#}
    while getopts abcdefghLkprsSuwxOGN opt;
          do
             case $opt in
               [abcdefghLkprsSuwxOGN]) test -$opt $f  || return 1;;
               *)return 1;;
             esac;
           done
 }

if testfile -fx file;then.
