title: generate javax.validation.ConstraintViolationException for unit test
body: <p>Springboot:  I got a mocked service and a method needs to return a javax.validation.ConstraintViolationException in order to properly unit test  the caller class.</p>
  
  <p>I cannot seem to find a way to generate a ConstraintViolationException or ConstraintViolation for that matter in Hibernate Validators.  </p>
  
  <p>Is there some solution I missing out?</p>
  
  <p>Thank you</p>
