Note that I also had a local test for pmu events:
for e in `$PERF list --raw-dump pmu`; do
   echo "Testing $e"
   result=$($PERF stat -v -e "$e" perf bench internals synthesize)
   if [[ "$result" =~ "$e" ]]; then
     echo "Event not printed: $e"
     exit 1
   fi
done

Is there any value in upstreaming this? I could not see same already 
there. Or else make your new script generic, so that it accepts an 
argument whether to test events or metrics or metricgroups
