Zend Framework 2 Doctrine 2模块 - 控制器单元测试中没有服务定位器

Question

这是我的情况.我正在开发Zend Framework 2应用程序.我正在使用Doctrine模块与MySQL数据库进行通信.它在应用程序中工作正常,我可以从我的控制器内的服务定位器加载实体管理器.

但是在我的控制器单元测试中,服务定位器不存在,因此处理数据库的所有测试都失败,并显示如下错误消息:

致命错误:get()在第19行的/Users/richardknop/Projects/myproject/module/Api/src/Api/Controller/UserController.php中调用非对象的成员函数

我把问题缩小到这个方法:

$this->getServiceLocator()

哪个适用于我的控制器,但在单元测试中返回NULL.

这是我的application.config.php:

<?php

return array(
    'modules' => array(
        'DoctrineModule',
        'DoctrineORMModule',
        'Api',
    ),
    'module_listener_options' => array(
        'config_glob_paths' => array(
            'config/autoload/{,*.}{global,local}.php',
        ),
        'module_paths' => array(
            './module',
            './vendor',
        ),
    ),
);

我的local.php文件包含数据库连接详细信息:

<?php

return array(
    'doctrine' => array(
        'connection' => array(
            'orm_default' => array(
                'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
                'params' => array(
                    'host'     => 'localhost',
                    'port'     => '3306',
                    'user'     => 'root',
                    'password' => 'root',
                    'dbname'   => 'mydb',
                ),
            ),
        ),
    ),
);

在我的module.config.php中我有:

'doctrine' => array(
    'driver' => array(
        __NAMESPACE__ . '_driver' => array(
            'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
            'cache' => 'array',
            'paths' => array(__DIR__ . '/../src/' . __NAMESPACE__ . '/Entity')
        ),
        'orm_default' => array(
            'drivers' => array(
                __NAMESPACE__ . '\Entity' => __NAMESPACE__ . '_driver'
            ),
        ),
    ),
),

在我的控制器中,我有这个方法来获取实体管理器:

private $_em;

private function _getEntityManager()
{
    if (null === $this->_em) {
        $this->_em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');
    }
    return $this->_em;
}

现在我的单元测试.这是bootstrap文件:

<?php

chdir(dirname(__DIR__));
include __DIR__ . '/../init_autoloader.php';
return Zend\Mvc\Application::init(include 'config/application.config.php');

我的控制器测试的setUp方法看起来像:

public function setUp()
{
    $this->_controller = new UserTokenController;
    $this->_request = new Request;
    $this->_routeMatch = new RouteMatch(array('controller' => 'user'));
    $this->_event = new MvcEvent();
    $this->_event->setRouteMatch($this->_routeMatch);
    $this->_controller->setEvent($this->_event);
}

然后,示例控制器单元测试如下所示:

public function testGetListHttpStatusCode()
{
    $response = $this->_controller->dispatch($this->_request);
    $this->assertEquals(405, $response->getStatusCode());
}

所有未连接到数据库的测试都在通过.我使用实体管理器的测试失败了,但是出现此错误:

致命错误:get()在第19行的/Users/richardknop/Projects/myproject/module/Api/src/Api/Controller/UserController.php中调用非对象的成员函数

这是第19行:

$this->_em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');

它失败的原因是$this->getServiceLocator()回报NULL.

任何想法如何解决这个问题？

不要这样做你的bootstrap.php

return Zend\Mvc\Application::init(include 'config/application.config.php');` in your 

但是像这样:

chdir('/path/to/application/root');

// if you're using composer to install zf2
include_once 'vendor/autoload.php';
// if not using composer initialize your custom autoloading here

$configuration = include('config/application.config.php');
$serviceManager = new ServiceManager(new ServiceManagerConfig(
    isset($configuration['service_manager']) ? $configuration['service_manager'] : array()
));
$serviceManager->setService('ApplicationConfig', $configuration);
$serviceManager->setFactory('ServiceListener', 'Zend\Mvc\Service\ServiceListenerFactory');

$moduleManager = $serviceManager->get('ModuleManager');
$moduleManager->loadModules();
$serviceManager->setAllowOverride(true);

$application = $serviceManager->get('Application');
$event  = new MvcEvent();
$event->setTarget($application);
$event->setApplication($application)
    ->setRequest($application->getRequest())
    ->setResponse($application->getResponse())
    ->setRouter($serviceManager->get('Router'));

然后,您可以在测试用例中创建静态方法来设置和获取事件......

namespace My;

class TestCase extends \Some\Basic\TestCase
{
    protected static $_mvcEvent;

    public static function setMvcEvent(MvcEvent $e) {

        self::$_mvcEvent = $e;
    }

    public static function getMvcEvent() {

        return self::$_mvcEvent;
    }
}

...并从bootstrap.php文件中注入它

My\TestCase::setMvcEvent($event); 

并且在你的setUp测试方法中只需做这样的事情

$this->_controller = new UserTokenController;
$this->_controller->setEvent(self::getMvcEvent());
$this->_controller->setServiceLocator(
    self::getMvcEvent()->getApplication()->getServiceManager()
);

还将event-> application中的请求等注入到控制器中......
