$testando->setEntityManagerName('teste');

require  __DIR__.'/../../api/vendor/autoload.php';

$config = new PhpFile(__DIR__. '/migrations.php'); // Or use one of the Doctrine\Migrations\Configuration\Configuration\* loaders

$conn = \Doctrine\DBAL\DriverManager::getConnection($connDBL);
$entityManager = new EntityManager($conn, $confiEntity);

return DependencyFactory::fromEntityManager($config, new ExistingEntityManager($entityManager));
