How to get the EntityManager inside of webtestcases in Symfony2

You can retrieve the DIC (Dependency Injection Container) through the Kernel, which is a protected member of the WebTestCase.

You could do this from within your WebTestCase:

$em = $this->kernel->getContainer()->get('doctrine.orm.entity_manager');

Update

From your own comment, there is even a shortcut for this (since you will have a client anyway):

$client = $this->getClient();
$container = $client->getContainer();

As is mentioned in the docs.

If you have your client, you can get the Entity Manager from it:

$em = $client->getContainer()->get('doctrine.orm.entity_manager');

Don't use `getEntityManager, it is deprecated since Symfony 2.1.

enjoy :)
