I decided to play with this a little more and wrote a quick implementation of Test::Exit.

Update - use Sidhekin 's Test::Trap instead

Test/Exit.pm

package Test::Exit;
use strict;
use warnings;
use Test::Builder;
use base qw( Exporter );
our @EXPORT = qw( exit_ok exit_nok exit_with );

my $test = Test::Builder->new;

my $exit_callback = sub {};

BEGIN {
    *CORE::GLOBAL::exit = sub { $exit_callback->(@_) };
}


sub exit_with(&$$) {
    my ($coderef, $expected_exit_code, $message) = @_;
    my $exit_called = 0;
    my $exit_code   = 0;

    $exit_callback = sub {
        $exit_called = 1;
        $exit_code = shift
    };

    $coderef->();
    if ($exit_called) {
        if (! $test->ok( $expected_exit_code == $exit_code, $message))
+ {
            $test->diag("expected $expected_exit_code but received $ex
+it_code");
        }
    }
    else {
        fail($message . " - exit not called");
    }
}
sub exit_ok(&$) {
    my ($coderef, $message) = @_;
    my $exit_called = 0;

    $exit_callback = sub { $exit_called = 1};
    $coderef->();
    $test->ok($exit_called == 1, $message);
}

sub exit_nok(&$) {
    my ($coderef, $message) = @_;
    my $exit_called = 0;

    $exit_callback = sub { $exit_called = 1};
    $coderef->();
    $test->ok($exit_called == 0, $message);
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
