Validations per se should be trustable, but you may want to check if the validation is present.
Put in other words, a good way to test something is as if it were a black box, abstracting the tests from the implementation, so for instance you may have a test that checks that a person model can’t be saved without a name, but don’t care about how the Person class performs that validation.
