Ola pessoal !!!
Sei que essa não é uma ferramenta muito usada ( encontra-se pouca coisa na internet) porém aqui no trabalho eu estou trabalhando com ela e é meio difícil informações sobre ela então espero que me ajudem.
Eu tenho uma entidade com relacionamento unidirecional, no site eles aconselham o uso da PoJoFixture eu à uso e sigo todos o exemplo porém estou tomando esse erro aqui "java.lang.RuntimeException: The N part (Collection) of a OneToMany collection must be Parametrized"
Alguem poderia me ajudar :assusta: esta complicado 
tenho ainda umas 65 entidades mais ou menos pra fazer
Segue o código:
//imports ..
public class AlbumTest extends PoJoFixture {
private static final Class<?>[] USED_ENTITIES = { Album.class,
Category.class, Frontend.class, MediaType.class, OrderType.class,
FrontendGroup.class, Region.class, Carrier.class, Price.class,
