Simple ZF2 Unit Tests for a controller using ZfcUser

I'm having issues trying to unit test an action which uses ZfcUser for authentication. I need some way to mock the ZfcUser Controller plugin but I'm not so sure how to do this. I've managed to successfully produce some unit tests for tables and models but the controller requires a lot of injected objects and is causing problems. Does anyone know how to set up the ZfcUser mocks to successfully unit test a controller?

Here is my test (copied from the ZF2 tutorial):

<?php
namespace SmsTest\Controller;

use SmsTest\Bootstrap;
use Sms\Controller\SmsController;
use Zend\Http\Request;
use Zend\Http\Response;
use Zend\Mvc\MvcEvent;
use Zend\Mvc\Router\RouteMatch;
use Zend\Mvc\Router\Http\TreeRouteStack as HttpRouter;
use PHPUnit_Framework_TestCase;

class SmsControllerTest extends PHPUnit_Framework_TestCase
{
    protected $controller;
    protected $request;
    protected $response;
    protected $routeMatch;
    protected $event;

    protected function setUp()
    {

        $serviceManager = Bootstrap::getServiceManager();

        $this->controller = new SmsController();
        $this->request    = new Request();
        $this->routeMatch = new RouteMatch(array('controller' => 'index'));
        $this->event      = new MvcEvent();
        $config = $serviceManager->get('Config');
        $routerConfig = isset($config['router']) ? $config['router'] : array();
        $router = HttpRouter::factory($routerConfig);
        $this->event->setRouter($router);
        $this->event->setRouteMatch($this->routeMatch);
        $this->controller->setEvent($this->event);
        $this->controller->setServiceLocator($serviceManager);
    }


    /* Test all actions can be accessed */

    public function testIndexActionCanBeAccessed()
    {
        $this->routeMatch->setParam('action', 'index');

        $result   = $this->controller->dispatch($this->request);
        $response = $this->co
