在 symfony 中测试存储库 [英] test a repository in symfony

问题描述

我的存储库中有以下方法，我想对其进行测试

I have the following method in my repository and I want to test it

public function myFindOne($id)
{
// On passe par le QueryBuilder vide de l'EntityManager pour l'exemple
  $qb = $this->_em->createQueryBuilder();

  $qb->select('a')
     ->from('xxxBundle:entity', 'a')
     ->where('a.id = :id')
     ->setParameter('id', $id);

    return $qb->getQuery()
              ->getResult();}

我在文档中找到了以下代码，但我看不懂

I found the following code in the documentation, but I could not understand it

// src/Acme/StoreBundle/Tests/Entity/ProductRepositoryFunctionalTest.php
namespace Acme\StoreBundle\Tests\Entity;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class ProductRepositoryFunctionalTest extends WebTestCase
{
    /**
     * @var \Doctrine\ORM\EntityManager
     */
    private $em;

    /**
     * {@inheritDoc}
     */
    public function setUp()
    {
        static::$kernel = static::createKernel();
        static::$kernel->boot();
        $this->em = static::$kernel->getContainer()
            ->get('doctrine')
            ->getManager()
        ;
    }

    public function testSearchByCategoryName()
    {
        $products = $this->em
            ->getRepository('AcmeStoreBundle:Product')
            ->searchByCategoryName('foo')
        ;

        $this->assertCount(1, $products);
    }

    /**
     * {@inheritDoc}
     */
    protected function tearDown()
    {
        parent::tearDown();
        $this->em->close();
    }
}

推荐答案

来自 Symfony 的官方文档，Repository方法测试如下:

From Symfony's official documentation, the Repository methods should be tested as follow:

// tests/AppBundle/Entity/ProductRepositoryTest.php
namespace Tests\AppBundle\Entity;

use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;

class ProductRepositoryTest extends KernelTestCase
{
    /**
     * @var \Doctrine\ORM\EntityManager
     */
    private $em;

    /**
     * {@inheritDoc}
     */
    protected function setUp()
    {
        self::bootKernel();

        $this->em = static::$kernel->getContainer()
            ->get('doctrine')
            ->getManager();
    }

    public function testSearchByCategoryName()
    {
        $products = $this->em
            ->getRepository('AppBundle:Product')
            ->searchByCategoryName('foo')
        ;

        $this->assertCount(1, $products);
    }

    /**
     * {@inheritDoc}
     */
    protected function tearDown()
    {
        parent::tearDown();

        $this->em->close();
    }
}
