getServiceLocator возвращает ноль в PHPUnittests

Я пытаюсь протестировать простой контроллер, который аутентифицирует пользователя с помощью LdapAdapter и массива ‘ldap’ из конфигурации приложения, но phpunit возвращает следующую ошибку:

Fatal error: Uncaught Error: Call to a member function get() on null in /var/www/html/app/module/Auth/src/Auth/Controller/AuthController.php:53
Stack trace:

Мой контроллер выглядит следующим образом:

<?php

namespace Auth\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\Authentication\Adapter\Ldap as AuthAdapter;
use Zend\Authentication\AuthenticationService;
use Zend\Authentication\Result;
use Auth\Form\AuthForm;
use Auth\Model\Auth;class AuthController extends AbstractActionController
{

public function loginAction()
{

$form = new AuthForm();

$request = $this->getRequest();
if ($request->isPost()) {
$auth = new Auth();

$form->setInputFilter($auth->getInputFilter());
$form->setData($request->getPost());

if ($form->isValid()){
$auth->exchangeArray($form->getData());

$values = $form->getData();

$result = $this->authenticate($values['username'], $values['password']);

switch($result->getCode()) {

case Result::SUCCESS:
return $this->redirect()->toRoute('home');
break;

case Result::FAILURE:
break;
}
}

}
return array('form' => $form);

}

public function authenticate($username, $password){

$options = $this->getServiceLocator()->get('Config');

$authAdapter = new AuthAdapter($options['ldap'],
'username',
'password');

$authAdapter
->setIdentity($username)
->setCredential($password);

$auth = new AuthenticationService();

$result = $auth->authenticate($authAdapter);

return $result;
}

private function debug($var){
echo '<pre>';
var_dump($var);
echo '</pre>';
exit();
}
}

TestCase:

namespace AuthTest\Controller;

use Zend\Test\PHPUnit\Controller\AbstractHttpControllerTestCase;
use Zend\Authentication\AuthenticationService;
use Auth\Controller\AuthController;class AuthControllerTest extends AbstractHttpControllerTestCase
{
protected $traceError = true;

public function setUp()
{
$this->setApplicationConfig(
include '/var/www/html/app/config/application.config.php'
);
parent::setUp();
}

public function testLoginAction()
{
#Basic Access to the page
$this->dispatch('/login');
$this->assertResponseStatusCode(200);

$data = array(
'identity' => 'myuser',
'credential' => 'mypassword',
);

$auth = new AuthController();
$auth->authenticate($data['identity'], $data['credential']);

$identity = new AuthenticationService();
$this->assertEquals($data['identity'], $identity->getIdentity());
}
}

BootStrap PHPUnittest:

<?php

namespace AuthTest;

use Zend\Loader\AutoloaderFactory;
use Zend\Mvc\Service\ServiceManagerConfig;
use Zend\ServiceManager\ServiceManager;
use RuntimeException;

error_reporting(E_ALL | E_STRICT);
chdir(__DIR__);

/**
* Test bootstrap, for setting up autoloading
*/
class Bootstrap
{
protected static $serviceManager;

public static function init()
{
$zf2ModulePaths = array(dirname(dirname(__DIR__)));
if (($path = static::findParentPath('vendor'))) {
$zf2ModulePaths[] = $path;
}
if (($path = static::findParentPath('module')) !== $zf2ModulePaths[0]) {
$zf2ModulePaths[] = $path;
}

static::initAutoloader();

// use ModuleManager to load this module and it's dependencies
$config = array(
'module_listener_options' => array(
'module_paths' => $zf2ModulePaths,
),
'modules' => array(
'Auth'
)
);

$serviceManager = new ServiceManager(new ServiceManagerConfig());
$serviceManager->setService('ApplicationConfig', $config);
$serviceManager->get('ModuleManager')->loadModules();
static::$serviceManager = $serviceManager;
}

public static function chroot()
{
$rootPath = dirname(static::findParentPath('module'));
chdir($rootPath);
}

public static function getServiceManager()
{
return static::$serviceManager;
}

protected static function initAutoloader()
{
$vendorPath = static::findParentPath('vendor');

if (file_exists($vendorPath.'/autoload.php')) {
include $vendorPath.'/autoload.php';
}

if (! class_exists('Zend\Loader\AutoloaderFactory')) {
throw new RuntimeException(
'Unable to load ZF2. Run `php composer.phar install`'
);
}

AutoloaderFactory::factory(array(
'Zend\Loader\StandardAutoloader' => array(
'autoregister_zf' => true,
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/' . __NAMESPACE__,
),
),
));
}

protected static function findParentPath($path)
{
$dir = __DIR__;
$previousDir = '.';
while (!is_dir($dir . '/' . $path)) {
$dir = dirname($dir);
if ($previousDir === $dir) {
return false;
}
$previousDir = $dir;
}
return $dir . '/' . $path;
}
}

Bootstrap::init();
Bootstrap::chroot();

В функциональных тестах это работает как ожидалось, но на php unittests ошибка появляется в строке 53 ‘$ options = $ this-> getServiceLocator () -> get (‘ Config ‘);’.

Итак, как использовать или настроить ServiceLocator для работы с phpunittests?
