-p should be changed to -n. Also, you don't need the /m modifier on the
regex.

see perldoc perlrun for explanation of -p and -n.

This will do it:
perl -n -e 'print if /Testing/m' test.txt
'-p' prints every line in the file so you'll see the matching lines 
twice (one because of '-p' and the other because of 'print') and the 
non-matching lines once (because of '-p').
Look  in 'perldoc perlrun'  for differences on '-p' and '-n'.
