Unit testing event triggered validation

I've created a custom class level validator. The valid() method has it's own session to query the table because I'm trying to validate that the insert or update won't put the data in an invalid state. This all seems to work.

The part that I'm struggling with is unit testing it. Is it even possible? In the test I persist entities to the database, triggering the validation. I annotated the tests with @Test(expected = ConstraintViolationException.class), but then both the validation and the test fails. Can the validator be unit tested in this way?

Without any information why the tests or validation failed, I think it will be hard to help you.

Is the Validator called on persist?
Has your validator implementation the session object?
How is the validator called inside your test?

It all depends on your test harness and how you set up things. You will need to be more specific.
