I tidied-up your script. This worked for me. 
#!/usr/bin/perl

use strict;
use warnings;
use Net::OpenSSH;

my $host     = 'host';
my $username = 'user';
my $password = 'pass';
my $cmd1     = 'cd /home/tests/Scripts/TestCaseScripts';
my $cmd2     = 'ls';

my $ssh = Net::OpenSSH->new($host,
          user        => $username, 
          password    => $password, 
          timeout     => 30,  
          strict_mode => 0,
          master_opts => [ -o => "StrictHostKeyChecking=no"]);
$ssh->error and 
  die "ssh failed: " . $ssh->error;
$ssh->system($cmd1) or
  die "remote command failed: " . $ssh->error;
my ($out,$err) = $ssh->capture($cmd1);
$ssh->error and
  die "remote command failed: " . $ssh->error;
$ssh->system($cmd2) or
  die "remote command failed: " . $ssh->error;
($out, $err) = $ssh->capture2($cmd2);
$ssh->error and
  die "remote command failed: " . $ssh->error;
