使用Arquillian和ShrinkWrap在抽象类中使用ShrinkWrap创建部署

Question

我试图通过定义一个抽象类来执行测试，这将使用Arquillian和ShrinkWrap为每个测试创建一个公共部署。在我的存储库中，我有一个EntityManager，它执行JPA操作。 UserRepository和CarRepository是相同的（User和Car除外）。对于UserRepositoryTest和CarRepositoryTest也是如此。

但是，CarRepositoryTest会因某种原因生成错误。你能帮我么？ =）

public abstract class AbstractRepositoryTest {

        @Inject
        protected UserRepository userRepository;

        @Inject
        protected GroupRepository groupRepository;

        @Inject
        protected CarRepository carRepository;

        protected DummyGenerator dg;

        protected UserRepositoryFindQuery qUser;

        protected CarRepositoryFindQuery qCar;

        @Deployment
        public static final Archive<?> createDeployment() {

                File[] libs = Maven
                                .resolver()
                                .loadPomFromFile("pom.xml")
                                .resolve("org.apache.commons:commons-lang3",
                                                "org.fluttercode.datafactory:datafactory",
                                                "org.dbunit:dbunit",
                                                "mysql:mysql-connector-java",

                                .addPackage(DummyGenerator.class.getPackage())
                                .addAsResource("test-persistence.xml",
