NAME

       App::Cmd::Tester - for capturing the result of running an app

VERSION

       version 0.318

SYNOPSIS

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

	 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');

	 is($result->error, undef, 'threw no exceptions');

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

	 is($result->output, '', 'absolutely no output with --quiet');

DESCRIPTION

       One of the reasons that user-executed programs are so often poorly tested is that they are hard to test.  App::Cmd::Tester is one of the
       tools App-Cmd provides to help make it easy to test App::Cmd-based programs.

       It provides one routine: test_app.

METHODS

   test_app
       Note: while "test_app" is a method, it is by default exported as a subroutine into the namespace that uses App::Cmd::Tester.  In other
       words: you probably don't need to think about this as a method unless you want to subclass App::Cmd::Tester.

	 my $result = test_app($app_class => @argv_contents);

       This will locally set @ARGV to simulate command line arguments, and will then call the "run" method on the given application class (or
       application).  Output to the standard output and standard error filehandles  will be captured.

       $result is an App::Cmd::Tester::Result object, which has methods to access the following data:

	 stdout - the output sent to stdout
	 stderr - the output sent to stderr
	 output - the combined output of stdout and stderr
	 error	- the exception thrown by running the application, or undef
	 run_rv - the return value of the run method (generally irrelevant)
	 exit_code - the numeric exit code that would've been issued (0 is 'okay')

NAME

       MooseX::App::Cmd - Mashes up MooseX::Getopt and App::Cmd.

SYNOPSIS

       See "SYNOPSIS" in App::Cmd.

	   package YourApp::Cmd;
	       use Moose;

	   extends qw(MooseX::App::Cmd);

	   package YourApp::Cmd::Command::blort;
	   use Moose;

	   extends qw(MooseX::App::Cmd::Command);

	   has blortex => (
	       traits => [qw(Getopt)],
	       isa => "Bool",
	       is  => "rw",
	       cmd_aliases   => "X",
	       documentation => "use the blortext algorithm",
	   );

	   has recheck => (
	       traits => [qw(Getopt)],
	       isa => "Bool",
	       is  => "rw",
	       cmd_aliases => "r",
	       documentation => "recheck all results",
	   );

	   sub execute {
	       my ( $self, $opt, $args ) = @_;

	       # you may ignore $opt, it's in the attributes anyway

	       my $result = $self->blortex ? blortex() : blort();

	       recheck($result) if $self->recheck;

	       print $result;
	   }

DESCRIPTION

       This module marries App::Cmd with MooseX::Getopt.

       Use it like App::Cmd advises (especially see App::Cmd::Tutorial), swapping App::Cmd::Command for MooseX::App::Cmd::Command.

       Then you can write your moose commands as moose classes, with MooseX::Getopt defining the options for you instead of "opt_spec" returning a
       Getopt::Long::Descriptive spec.
