SYNOPSIS

13         use Test::More tests => 4;
14         use App::Cmd::Tester::CaptureExternal;
15
16         use YourApp;
17
18         my $result = test_app(YourApp => [ qw(command --opt value) ]);
19
20         like($result->stdout, qr/expected output/, 'printed what we expected');
21
22         is($result->stderr, '', 'nothing sent to sderr');
23
24         ok($result->output, "STDOUT concatenated with STDERR");
25

DESCRIPTION

27       App::Cmd::Tester provides a useful scaffold for testing applications,
28       but it is unable to capture output generated from any external
29       subprograms that are invoked from the application.
30
31       This subclass uses an alternate mechanism for capturing output
32       (Capture::Tiny) that does capture from external programs, with one
33       major limitation.
34
35       It is not possible to capture externally from both STDOUT and STDERR
36       while also having appropriately interleaved combined output.
37       Therefore, the "output" from this subclass simply concatenates the two.
38
39       You can still use "output" for testing if there is any output at all or
40       for testing if something appeared in either output stream, but you
41       can't rely on the ordering being correct between lines to STDOUT and
42       lines to STDERR.

PERL VERSION SUPPORT

45       This module has a long-term perl support period.  That means it will
46       not require a version of perl released fewer than five years ago.
47
48       Although it may work on older versions of perl, no guarantee is made
49       that the minimum required version will not be increased.  The version
50       may be increased for any reason, and there is no promise that patches
51       will be accepted to lower the minimum required perl.
