ZF2教程专辑PHPUnit测试失败，未定义属性：AlbumTest \ Model \ AlbumTableTest :: $ controller

Question

我正在构建ZF2专辑教程应用程序，当我进行单元测试时，即使我再次重建应用程序，我仍然会收到相同的错误。谁能告诉我这里发生了什么？我在这里倾倒所有相关信息以提供帮助。错误是：

PHPUnit 3.7.10 by Sebastian Bergmann.

    public function testGetAlbumTableReturnsAnInstanceOfAlbumTable() {
        $this->assertInstanceOf('Album\Model\AlbumTable', $this->controller->getAlbumTable());

}

?>

getAlbumTable在AlbumController中如下：

<?php

namespace Album\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

class AlbumController extends AbstractActionController {

    protected $albumTable;

    public function indexAction() {
        return new ViewModel(array(
                    'albums' => $this->getAlbumTable()->fetchAll(),
                ));
    }

    public function addAction() {

    }

    public function editAction() {

    }

    public function deleteAction() {

    }

    public function getAlbumTable() {
        if (!$this->albumTable) {
            $sm = $this->getServiceLocator();
            $this->albumTable = $sm->get('Album\Model\AlbumTable');
        }
        return $this->albumTable;
    }

}

?>

而且AlbumTable是：

<?php
namespace Album\Model;

use Zend\Db\TableGateway\TableGateway;

class AlbumTable
{
    protected $tableGateway;

    public function __construct(TableGateway $tableGateway)
    {
        $this->tableGateway = $tableGateway;
    }

    public function fetchAll()
    {
        $resultSet = $this->tableGateway->select();
        return $resultSet;
    }

    public function getAlbum($id)
    {
        $id  = (int) $id;
        $rowset = $this->tableGateway->select(array('id' => $id));
        $row = $rowset->current();
        if (!$row) {
            throw new \Exception("Could not find row $id");
        }
        return $row;
    }

    public function saveAlbum(Album $album)
    {
        $data = array(
            'artist' => $album->artist,
            'title'  => $album->title,
        );

        $id = (int)$album->id;
        if ($id == 0) {
            $this->tableGateway->insert($data);
        } else {
            if ($this->getAlbum($id)) {
                $this->tableGateway->update($data, array('id' => $id));
            } else {
                throw new \Exception('Form id does not exist');
            }
        }
    }

    public function deleteAlbum($id)
    {
        $this->tableGateway->delete(array('id' => $id));
    }
}
?>

Answer 1

您认为需要添加一些设置代码并将其与AlbumControllerTest.php进行比较是正确的，这是正确的。

正如错误消息所述，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

并使用以下内容对其进行初始化：

$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');

总结一下，你做了正确的事，但你不需要所有额外的代码。你可以逃脱：

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

的开头

Answer 2

虽然我不确定这是否是适当的解决方案，但我解决了错误。我查看了AlbumControllerTest而不是AlbumTableTest。它有一个创建控制器类的安装方法。我复制了设置代码以及相应的use语句和变量声明，目前我正在研究下一期......

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);
    }

Answer 3

您忘记在Module.php中添加新的import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，我在同样的事情上花了15分钟......
