app::cmd::tester
App::Cmd::Tester(3pm) User Contributed Perl Documentation App::Cmd::Tester(3pm)
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')
