NAME
       App::Cmd::Tester::CaptureExternal - Extends App::Cmd::Tester to capture from external subprograms

VERSION
       version 0.318

SYNOPSIS
	 use Test::More tests => 4;
	 use App::Cmd::Tester::CaptureExternal;

	 use YourApp;

	 my $result = test_app(YourApp => [ qw(command --opt value) ]);

	 like($result->stdout, qr/expected output/, 'printed what we expected');

	 is($result->stderr, '', 'nothing sent to sderr');

	 ok($result->output, "STDOUT concatenated with STDERR");

DESCRIPTION
       App::Cmd::Tester provides a useful scaffold for testing applications, but it is unable to capture output generated from any external
       subprograms that are invoked from the application.

       This subclass uses an alternate mechanism for capturing output (Capture::Tiny) that does capture from external programs, with one major
       limitation.

       It is not possible to capture externally from both STDOUT and STDERR while also having appropriately interleaved combined output.
       Therefore, the "output" from this subclass simply concatenates the two.

       You can still use "output" for testing if there is any output at all or for testing if something appeared in either output stream, but you
       can't rely on the ordering being correct between lines to STDOUT and lines to STDERR.
