如何在Symfony 5.4中的Phpunit testcase中访问EntityManager？

Question

在Symfony 5.4上，我正在对REST API进行测试。 当我尝试访问实体管理器时，我总是会遇到错误，

我遵循此文档：

这是我的测试代码：

<?php
namespace App\Tests;

use App\Repository\LocationRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Component\HttpFoundation\Response;

class DataTest extends WebTestCase     // WebTestCase  (not KernelTestCase)
{
    private EntityManagerInterface $entityManager;
    private LocationRepository $locationRepository;

    protected function setUp(): void
    {
        $kernel = self::bootKernel();
        $this->entityManager = $kernel->getContainer()
            ->get('doctrine')
            ->getManager();
        $this->locationRepository = $this->entityManager->get(LocationRepository::class);
    }

    protected function tearDown(): void
    {
        parent::tearDown();

        // doing this is recommended to avoid memory leaks
        $this->entityManager->close();
        $this->entityManager = null;
    }

    public function test401(): void
    {
        $client = static::createClient();
        $crawler = $client->request('GET', '/api/locations');
        $response = $client->getResponse();
        $this->assertResponseStatusCodeSame(401);
    }
...

我得到此错误：

Testing App\Tests\DataTest
EEEE                                                                4 / 4 (100%)

There were 4 errors:

1) App\Tests\DataTest::test401
Error: Call to undefined method ContainerDyLAo2g\EntityManager_9a5be93::get()

如何解决此问题？

Answer 1

在 WebTestcase 中，您可以这样访问Entity Manager，

$this->entityManager = static::getContainer()->get(EntityManagerInterface::class)

您也可以在此处查看文档 https://symfony.com/doc/current/testing.html#retrieving-services-in-the-the-test

Answer 2

EntityManagerInterface上没有方法 get（）。使用方法 getRepository（string $ className）获取存储库：

$this->locationRepository = $this->entityManager>getRepository(LocationEntity::class);
