Help with failing Grails test - domain methods not working?
class AchievementsService {

    static transactional = true

    public void onEvent(String eventName, User user) {
        def event = Event.findByName(eventName)
        if (!event) {
            event = new Event(name: eventName, autoConfigured: true)
            event.save()
        }
    }
}

class AchievementsServiceTests extends GrailsUnitTestCase {
    AchievementsService service
    User user
    protected void setUp() {
        super.setUp()
        service = new AchievementsService()
        user = new User(username:"marty",password: "password")
        mockDomain(User,[user])
    }
