accessing entity manager inside phpunittest - php

Question

I have the following unit test code in symfony:
<?php
// src/Acme/DemoBundle/Tests/Utility/CalculatorTest.php
namespace Shopious\MainBundle\Tests;
class ShippingCostTest extends \PHPUnit_Framework_TestCase
{
public function testShippingCost()
{
$em = $this->kernel->getContainer()->get('doctrine.orm.entity_manager');
$query = $em->createQueryBuilder();
$query->select('c')
->from("ShopiousUserBundle:City", 'c');
$result = $query->getQuery()->getResult();
var_dump($result);
}
}
and I am trying to access the entity manager here, howver it always gives me this error:
Undefined property: Acme\MainBundle\Tests\ShippingCostTest::$kernel

Answer 1

To achieve this you need to create a base test class (let's call it KernelAwareTest) with following contents:
<?php
namespace Shopious\MainBundle\Tests;
require_once dirname(__DIR__).'/../../../app/AppKernel.php';
/**
* Test case class helpful with Entity tests requiring the database interaction.
* For regular entity tests it's better to extend standard \PHPUnit_Framework_TestCase instead.
*/
abstract class KernelAwareTest extends \PHPUnit_Framework_TestCase
{
/**
* #var \Symfony\Component\HttpKernel\Kernel
*/
protected $kernel;
/**
* #var \Doctrine\ORM\EntityManager
*/
protected $entityManager;
/**
* #var \Symfony\Component\DependencyInjection\Container
*/
protected $container;
/**
* #return null
*/
public function setUp()
{
$this->kernel = new \AppKernel('test', true);
$this->kernel->boot();
$this->container = $this->kernel->getContainer();
$this->entityManager = $this->container->get('doctrine')->getManager();
$this->generateSchema();
parent::setUp();
}
/**
* #return null
*/
public function tearDown()
{
$this->kernel->shutdown();
parent::tearDown();
}
/**
* #return null
*/
protected function generateSchema()
{
$metadatas = $this->getMetadatas();
if (!empty($metadatas)) {
$tool = new \Doctrine\ORM\Tools\SchemaTool($this->entityManager);
$tool->dropSchema($metadatas);
$tool->createSchema($metadatas);
}
}
/**
* #return array
*/
protected function getMetadatas()
{
return $this->entityManager->getMetadataFactory()->getAllMetadata();
}
}
Then your own test class will be extended from this one:
<?php
namespace Shopious\MainBundle\Tests;
use Shopious\MainBundle\Tests\KernelAwareTest;
class ShippingCostTest extends KernelAwareTest
{
public function setUp()
{
parent::setUp();
// Your own setUp() goes here
}
// Tests themselves
}
And then use parent's class methods. In your case, to access entity manager, do:
$entityManager = $this->entityManager;
