If you always want to use h2, you could just simply build the string using 

If you wanted to inject different JPA providers, you could certainly use 
Guice for that (since you posted here) - I have a HibernateSessionFactory 
that provides a session per request like this:

private Session provideSession() {

And then for my jUnit tests I have:

private Session provideSession() {

in a

public class TestGuiceModule extends AbstractModule

Would that fit your use case?
