Symfony2: Testing entity validation constraints

Question

Does anyone have a good way to unit test an entity\'s validation constraints in Symfony2?

Ideally I want to have access to the Dependency Injection Container within

I liked Kasheens answer, but it doesn't work for Symfony 2.3 anymore. There are little changes:

use Symfony\Component\Validator\Validation;

and

$validator = Validation::createValidatorBuilder()->getValidator();

If you want to validate Annotations for instance, use enableAnnotationMapping() like below:

$validator = Validation::createValidatorBuilder()->enableAnnotationMapping()->getValidator();

the rest stays the same:

$errors = $validator->validate($entity);
$this->assertEquals(0, count($errors));
