Unit testing validator constraints with symfony2.3

Question

I would like to make a test unit using constraint but I have this error when running my test

This are my different classes and the obtaining error after running phpunit

 use Symfony\\Component\\Validator\\Constraint; /** * @Annotation */ class Age18 extends Constraint { public $message = 'Vous devez avoir 18 ans.'; } use Symfony\\Component\\Validator\\Constraint; use Symfony\\Component\\Validator\\ConstraintValidator; class Age18Validator extends ConstraintValidator { public function validate($dateNaissance, Constraint $constraint) { if ($dateNaissance > new \\DateTime("18 years ago")) { $this->context->addViolation($constraint->message); } } } use Symfony\\Component\\Translation\\TranslatorInterface; use Symfony\\Component\\Validator\\Constraint; use Symfony\\Component\\Validator\\ConstraintValidator; class Age18ValidatorTest extends \\PHPUnit_Framework_TestCase { private $constraint; public function setUp() { $this->constraint = $this->getMock('Symfony\\Component\\Validator\\Constraint'); } public function testValidate() { /*ConstraintValidator*/ $validator = new Age18Validator(); $context = $this ->getMockBuilder('Symfony\\Component\\Validator\\ExecutionContext') ->disableOriginalConstructor() ->getMock('Age18Validator', array('validate')); $context->expects($this->once()) ->method('addViolation') ->with('Vous devez avoir 18 ans.'); $validator->initialize($context); $validator->validate('10/10/2000', $this->constraint); } public function tearDown() { $this->constraint = null; } } 

 Expectation failed for method name is equal to <string:addViolation> when invoked 1 time(s). Method was expected to be called 1 times, actually called 0 times. 

Please could you help me to solve this problem?

Thanks you!!

Check the type of your element: in the validator class you use the comparator between two DateTime object but in the test you pass a string to the validator.

This is my test class:

namespace Acme\DemoBundle\Tests\Form;

use Acme\DemoBundle\Validator\Constraints\Age18;
use Acme\DemoBundle\Validator\Constraints\Age18Validator;

class Age18ValidatorTest extends \PHPUnit_Framework_TestCase
{
    private $constraint;
    private $context;

    public function setUp()
    {
        $this->constraint = new Age18();
        $this->context = $this->getMockBuilder('Symfony\Component\Validator\ExecutionContext')->disableOriginalConstructor()->getMock();
    }

    public function testValidate()
    {


        /*ConstraintValidator*/
        $validator = new Age18Validator();
        $validator->initialize( $this->context);

        $this->context->expects($this->once())
            ->method('addViolation')
            ->with($this->constraint->message,array());
        $validator->validate(\Datetime::createFromFormat("d/m/Y","10/10/2000"), $this->constraint);
    }

    public function tearDown()
    {
        $this->constraint = null;
    }
}

Hope this help
