How to Test Doctrine Repositories
Warning: You are browsing the documentation for Symfony 3.x, which is no longer maintained.
Read the updated version of this page for Symfony 7.2 (the current stable version).
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 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 KernelTestCase,
which makes all of this quite easy:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46
// tests/AppBundle/Repository/ProductRepositoryTest.php
namespace Tests\AppBundle\Repository;
use AppBundle\Entity\Product;
use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;
class ProductRepositoryTest extends KernelTestCase
{
/**
* @var \Doctrine\ORM\EntityManager
*/
private $entityManager;
/**
* {@inheritDoc}
*/
protected function setUp()
{
$kernel = self::bootKernel();
$this->entityManager = $kernel->getContainer()
->get('doctrine')
->getManager();
}
public function testSearchByCategoryName()
{
$products = $this->entityManager
->getRepository(Product::class)
->searchByCategoryName('foo')
;
$this->assertCount(1, $products);
}
/**
* {@inheritDoc}
*/
protected function tearDown()
{
parent::tearDown();
$this->entityManager->close();
$this->entityManager = null; // avoid memory leaks
}
}
