If you're not interested in performance, but just want to log when which subroutine is called, then you can steal both code references and replace them with a routine of your own. Something like this:
{ # start a scope here to prevent interference with anything else
my $test = \&main::test1; # only need this once as they are the same
*main::test1 = sub { print "<main::test1> @_\n"; goto &$test };
*main::test2 = sub { print "<main::test2> @_\n"; goto &$test };
} # $test kept because still refs in the anonymous subs
Hope this helps.
