if ( $output1 || $output2 =~ m/\d+\.\d+/gm ) {

That probably isn't doing what you think it is. You are testing if $output1 is true or if $output2 matches the regex. It's not entirely clear to me what you want here but this is an SSCCE which illustrates one simplistic regex matching against one of your samples but not the other. Perhaps that's what you want.

use warnings;

use Test::More tests => 2;
