test a repository in symfony - php

Question

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();}
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();
}
}

Answer 1

To see what you should edit in this code, the testSearchByCatergory() should be a good start. In this example, it gets the result of the tested method into $products and checks that this collection contains only one element.
So I guess your test would be to test that the returned object is the one you expect to be returned. But heh, like #cheesemacfly said, your repo is kinda the same as findOne[ById]()... Oh and BTW, you should check up phpunit [EN] (Or in FR, as I saw in your comment) documentation to see how you should make it run.
Cheers. :)

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();
}
}
