Error when using YEAR, MONTH, DAY mysql functions in LiipFunctionalTest bundle

I'm using DAY, MONTH, YEAR mysql's functions (http://ift.tt/1B6tPkG) with LiipFunctionalTestBundle. When I run the test I'm getting:

SQLSTATE[HY000]: General error: 1 no such function: YEAR

At the end, the test failed. I guess it's because of that.

This is my config_test file:

imports:
    - { resource: config_dev.yml }

framework:
    test: ~
    session:
        storage_id: session.storage.filesystem
        name: MOCKSESSID

web_profiler:
    toolbar: false
    intercept_redirects: false

swiftmailer:
    disable_delivery: true

liip_functional_test: 
  cache_sqlite_db: true
  authentication:
    username: "root"
    password: "admin"

doctrine:
  dbal:
    default_connection: default
    connections:
      default:
        driver:   pdo_sqlite
        path:     %kernel.cache_dir%/test.db
  orm:
    dql: 
      datetime_functions:
        YEAR: DoctrinceExtensions\Query\Mysql\Year
        MONTH: DoctrinceExtensions\Query\Mysql\Month
        DAY: DoctrinceExtensions\Query\Mysql\Day           

In my code I use them as:

$em = $this->getDoctrine()->getManager();
$emConfig = $em->getConfiguration();
$emConfig->addCustomDatetimeFunction('YEAR', 'DoctrineExtensions\Query\Mysql\Year');
$emConfig->addCustomDatetimeFunction('MONTH', 'DoctrineExtensions\Query\Mysql\Month');
$emConfig->addCustomDatetimeFunction('DAY', 'DoctrineExtensions\Query\Mysql\Day');

....
$em = $this->get('doctrine.orm.entity_manager');
$dql = $em->createQuery('SELECT um FROM Acme\AcmeBundle\Entity\Menu um WHERE 
                  um.user = :id and 
                  YEAR(um.day) = :year and 
                  MONTH(um.day) = :month and 
                  DAY(um.day) = :day');
      $dql->setParameter('id', $id);
      $dql->setParameter('year', $now->format("Y"));
      $dql->setParameter('month', $now->format("m"));
      $dql->setParameter('day', $now->format("d"));

If I run the application I don't have problems.
