How do you test code that uses perl -d debugger?

Testing Perl code that utilizes the Perl debugger (perl -d) can be challenging but is essential for debugging and ensuring the correctness of your code. Here’s how you can effectively test your Perl scripts using the debugger.


      # Example Perl code to test using the debugger
      #!/usr/bin/perl
  
      use strict;
      use warnings;

      sub add {
          my ($a, $b) = @_;
          return $a + $b;
      }

      my $result = add(2, 3);
      print "Result: $result\n";
