我正在构建 ZF2 相册教程应用程序，当我进行单元测试时，即使我再次重建了应用程序，我也始终收到相同的错误。 有人可以告诉我这里发生了什么吗？ 我在这里倾倒所有相关信息以提供帮助。 错误是：

getAlbumTable 位于 AlbumController 中，如下所示：

if (!$this->albumTable) {
$sm = $this->getServiceLocator();
$this->albumTable = $sm->get('Album'Model'AlbumTable');
}
return $this->albumTable;
}
}
?>
而专辑表是：
<?php
namespace Album'Model;
use Zend'Db'TableGateway'TableGateway;

return $row;
}
public function saveAlbum(Album $album)
{

$id = (int)$album->id;
if ($id == 0) {
$this->tableGateway->insert($data);

throw new 'Exception('Form id does not exist');
}
}
}
public function deleteAlbum($id)
{
$this->tableGateway->delete(array('id' => $id));
}
}
?>
模块.php为：
<?php
namespace Album;
class Module
{
public function getAutoloaderConfig()
{
return array(
'Zend'Loader'ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',

$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
return new TableGateway('album', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
}
?>
module.config.php 是：

application.config.php 是：

您正确地假设您需要添加一些设置代码并将其与AlbumControllerTest.php进行比较是个好主意。
如错误消息所述，问题是AlbumTableTest对象没有controller属性。 因此，我们需要使用以下方法添加属性：
$protected controller
并使用以下方法对其进行初始化：
$this->controller = new AlbumController()
此外，我们需要初始化 serviceManager 属性并设置其 serviceLocator 属性，以便以下调用在控制器的 getAlbumTable 方法中有意义：
$sm = $this->getServiceLocator();
$this->albumTable = $sm->get('Album'Model'AlbumTable');
总而言之，你做了正确的事情，但你不需要所有额外的代码。 您可以侥幸逃脱：
use AlbumTest'Bootstrap;
use Album'Controller'AlbumController;
use Album'Model'AlbumTable;
use Album'Model'Album;
use Zend'Db'ResultSet'ResultSet;
use PHPUnit_Framework_TestCase;
class AlbumTableTest extends PHPUnit_Framework_TestCase
{
protected $controller;
protected function setUp()
{
$serviceManager = Bootstrap::getServiceManager();
$this->controller = new AlbumController();
$this->controller->setServiceLocator($serviceManager);
}
....
在AlbumTableTest.php开始时
虽然我不确定此时这是否是适当的修复程序，但我解决了错误。 我研究了AlbumControllerTest而不是AlbumTableTest。 它具有创建控制器类的设置方法。 我复制了设置代码以及适当的 use 语句和变量声明，目前，我正在下一个问题......
我仍然对更好的答案感兴趣！
我复制(添加(的内容包括：
use AlbumTest'Bootstrap;
use Album'Controller'AlbumController;
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 AlbumTableTest extends PHPUnit_Framework_TestCase {
protected $controller;
protected $request;
protected $response;
protected $routeMatch;
protected $event;
protected function setUp()
{
$serviceManager = Bootstrap::getServiceManager();
$this->controller = new AlbumController();
$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);
}
您忘了在模块.php中添加新的导入语句。文件的开头应如下所示：
namespace Album;
use Album'Model'Album;
use Album'Model'AlbumTable;
use Zend'Db'ResultSet'ResultSet;
use Zend'Db'TableGateway'TableGateway;
class Module
{
//...
容易跳过，很难找到，我在同一件事上花了 15 分钟......
