How to test Doctrine Repositories

Unit testing Doctrine repositories in a Symfony project is not recommended. When you're dealing with a repository, you're really dealing with something that's meant to be tested against a real database connection.

Fortunately, you can easily test your queries against a real database, as described below.

Functional Testing

If you need to actually execute a query, you will need to boot the kernel to get a valid connection. In this case, you'll extend the WebTestCase, which makes all of this quite easy:

// 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;

    public function setUp()
    {
        $kernel = static::createKernel();
        $kernel->boot();
        $this->em = $kernel->getContainer()->get('doctrine.orm.entity_manager');
    }

    public function testProductByCategoryName()
    {
        $results = $this->em
            ->getRepository('AcmeStoreBundle:Product')
            ->searchProductsByNameQuery('foo')
            ->getResult()
        ;

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