How to test Symfony2 models using PHPUnit - php

Question

I've been trying to test a model in a Symfony2 project, but I don't know how to get the entity manager to save and retrive records.
Can anyone point me to the right docs for this?

Answer 1

In order to test your models, you can use setUp() method. link to docs
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
class MyModelTest extends WebTestCase
{
/**
* #var EntityManager
*/
private $_em;
protected function setUp()
{
$kernel = static::createKernel();
$kernel->boot();
$this->_em = $kernel->getContainer()->get('doctrine.orm.entity_manager');
$this->_em->beginTransaction();
}
/**
* Rollback changes.
*/
public function tearDown()
{
$this->_em->rollback();
}
public function testSomething()
{
$user = $this->_em->getRepository('MyAppMyBundle:MyModel')->find(1);
 }
Hope this helps you

Answer 2

Symfony2 models are expected to be domain objects that represent domain models in the code.
domain objects should be defined purely to implement the business
behavior of the corresponding domain concept, rather than be defined
by the requirements of a more specific technology framework. -- Domain-driven design - Wikipedia, the free encyclopedia
Domain objects (and its tests) should not depend on Symfony2 APIs and Doctrine APIs except if you really want to test themselves.
Writing Symfony2 unit tests is no different than writing standard PHPUnit unit tests. -- Symfony - Testing
You can test business logic (processes, rules, behaviors, etc.) represented in domain objects with PHPUnit (or Behat) and usually test doubles.

use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Output\NullOutput;
use Symfony\Component\Console\Input\ArrayInput;

public function setUp()
{

// drop the database
$command = new DropDatabaseDoctrineCommand();
$this->application->add($command);
$input = new ArrayInput(array(
'command' => 'doctrine:database:drop',
'--force' => true
));
$command->run($input, new NullOutput());
// we have to close the connection after dropping the database so we don't get "No database selected" error
$connection = $this->application->getKernel()->getContainer()->get('doctrine')->getConnection();
if ($connection->isConnected()) {
$connection->close();
}
// create the database
$command = new CreateDatabaseDoctrineCommand();
$this->application->add($command);
$input = new ArrayInput(array(

$command->run($input, new NullOutput());
// create schema
$command = new CreateSchemaDoctrineCommand();
$this->application->add($command);
$input = new ArrayInput(array(
'command' => 'doctrine:schema:create',

$command->run($input, new NullOutput());
// get the Entity Manager
$this->em = static::$kernel->getContainer()
->get('doctrine')
->getManager();
// load fixtures
$client = static::createClient();
$loader = new \Symfony\Bridge\Doctrine\DataFixtures\ContainerAwareLoader($client->getContainer());
$loader->loadFromDirectory(static::$kernel->locateResource('#IbwJobeetBundle/DataFixtures/ORM'));
$purger = new \Doctrine\Common\DataFixtures\Purger\ORMPurger($this->em);
$executor = new \Doctrine\Common\DataFixtures\Executor\ORMExecutor($this->em, $purger);
$executor->execute($loader->getFixtures());
}
public function testFunction()
{
// here you test save any object or test insert any object
}
protected function tearDown()
{
parent::tearDown();
$this->em->close();
}
}
