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 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
}
}
