ScalaTest does shrinking itself and doesn't care how input is generated, so if, for example, a ScalaCheck generator is used to generate only positive numbers, ScalaTest still can shrink it to zero, so an additional constraint is needed to discard invalid input. (Although I don't remember anyone else using generators is Scala at all.)
