perhaps: 
#!/usr/bin/perl -w
use strict;

use Test::Simple tests => 3;

systest( 0, ("who") );
systest( 0, ("who", "am", "i") );
systest( 1, ("bash", "-c", "exit 1") );

sub systest {
    my $expected = shift;
    my @cmd = @_;
    system @cmd;
    my $sysres = $? >> 8;
    ok( $sysres == $expected, "'@cmd' returned $sysres" );
}

The disadvantage here is the mixed output from the test script and the system() calls. I cannot simply add ">/dev/null" to @cmd. My real script parameters rely on not using a Shell for system().
