Personally, i think this is as expected and you should change you code to not print from inside your subroutine. Your subroutine should collect data and store it in a scalar and return that instead of just printing. This is a common mistake people make, thinking that subroutines should print directly to STDOUT - sometimes they should, but most of the time you are better off capturing the output and returning it. This helps lead to more reusable code. Besides, are you more interested in testing the output, or the message string? 
use Test::More qw(no_plan);

ok(test_foo() eq "bar");

sub print_foo_message {
    print "foo";
}
sub test_foo { 
    return "bar";
}
