How to test Symfony2 models using PHPUnit

开发者_运维百科

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?

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

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.
