in reply to Re: How to test exit? - override CORE::GLOBAL::exit
in thread How to test exit?

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); } 1; =head1 NAME Test::Exit - Tests whether exit was called =head2 exit_ok exit_ok { exit; }, 'assert that exit was called'; =head2 exit_nok exit_nok { }, 'assert that exit was not called'; =head2 exit_with exit_with { exit 2 }, 2, 'expect exit(2)'; =cut
test.pl
use strict; use warnings; use Test::More (tests => 3); use Test::Exit; exit_ok { exit } "exit called"; exit_nok { } "exit not called"; exit_with { exit 2; } 2, 'exit code = 2';
