Suggest a JPA Unit test framework

Question

How to unit test JPA code? is there any way to generate Unit Test case itself?

I'm in the middle of trying out OpenEJB (http://openejb.apache.org/) for my ongoing project. It's an embeddable container with support for EJB 3.0 (and partially 3.1). My first impression of it is fairly good.
