Access entity manager in Zend Framework 2 unit tests

In order to access the entity manager in your unit tests you will have to make your PHPUnit bootstrap file a little bit more complex. You will need to access the entity manager if you are using Doctrine module together with Zend Framework 2.

Here is what I have done:

<?php

use Zend\ServiceManager\ServiceManager,
    Zend\Mvc\Service\ServiceManagerConfig;

class Bootstrap
{
    static public $config;
    static public $sm;
    static public $em;

    static public function go()
    {
        chdir(dirname(__DIR__));
        include __DIR__ . '/../init_autoloader.php';
        self::$config = include 'config/application.config.php';
        Zend\Mvc\Application::init(self::$config);
        self::$sm = self::getServiceManager(self::$config);
        self::$em = self::getEntityManager(self::$sm);
    }

    static public function getServiceManager($config)
    {
        $serviceManager = new ServiceManager(new ServiceManagerConfig);
        $serviceManager->setService('ApplicationConfig', $config);
        $serviceManager->get('ModuleManager')->loadModules();
        return $serviceManager;
    }

    static public function getEntityManager($serviceManager)
    {
        return $serviceManager->get('doctrine.entitymanager.orm_default');
    }
}

Bootstrap::go();

And then in your unit tests you can access the entity manager simply by:

Bootstrap:$em

That was quite easy actually.
