Hibernate-validatior: Why is the MyCustomConstraintValidator not a managed instance in the weld-se container?

Hello All,
In our project we are testing jpa database access with the weld-junit5 framework. The EntityManager is injected via CDI into the test class. A Bean Validation (hibernate-validator) is present in the classpath and the entity is annotated with a custom validator which implements ConstraintValidator.
So everythink works as expected and when the em.persist(entity) function is called the isValid(…) Method is also called.
The problem is, that the isValid( ) method needs a cdi-injected intstance:

public class MyValidator implements ConstraintValidator<MyValidation, TestEntity> {

    @Inject
    private MyDao myDao; // is null

    @Override
    public void initialize(MyValidation constraintAnnotation) {
        System.out.println("init...");
    }

    @Override
    public boolean isValid(TestEntity testEntity, ConstraintValidatorContext constraintValidatorContext) {
        //null pointer exception is thrown here
        return myDao.isValid();
    }

    public MyDao getMyDao() {
        return myDao;
    }
}

The question is now: How can I turn this custom validator to a cdi bean managed instance? Is there way to get the validator instance via a simple method in order to register it with the BeanManager?

Another approach could be this way (hibernate-validator-cdi):

...
import org.hibernate.validator.cdi.HibernateValidator;
import org.hibernate.validator.cdi.ValidationExtension;
...
    @Inject
    @HibernateValidator
    private Validator validator;

...

 @Produces
    public EntityManagerFactory produceEntityManagerFactory() {
        // how can I force that the em uses the injected validator?
    }

How can I force that the em uses the injected validator?

Thanks in advance for every hint,

Tom

This solution uses the injected validation:

@ApplicationScoped
public class EntityManagerFactoryProducer {

    @Inject
    private BeanManager beanManager;

    @Inject
    @HibernateValidator
    private ValidatorFactory validatorFactory;

    @Produces
    public EntityManagerFactory produceEntityManagerFactory() {
        Map<String, Object> props  = new HashMap();
        props.put("javax.persistence.bean.manager", beanManager);
        props.put("javax.persistence.validation.factory", validatorFactory);
        EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("entityManagerFactory", props);

        return entityManagerFactory;
    }

    public void close(@Disposes EntityManagerFactory entityManagerFactory) {
        entityManagerFactory.close();
    }
}
