=head1 NAME

Catalyst::Test::MessageDriven - test message-driven Catalyst apps

=head1 DESCRIPTION

Derived from Catalyst::Test, this module provides a way to run tests
against message-driven Catalyst applications - those with
Catalyst::Controller::MessageDriven-based controllers, and expect to
run with Catalyst::Engine::Stomp.

=head1 SYNOPSIS

  BEGIN { use_ok 'Catalyst::Test::MessageDriven', 'SomeApp' };

  my $req = '... some message text ...';
  my $queue = 'somequeue';
  my $res = request($queue, $req);
  ok($res);

=head1 EXPORTS

=head2 request(queue, message)

This function accepts a queue and a message, and runs the request in
that context. Returns a response object.

=head1 TODO

Some test wrappers - successful / error message conditions?
