My setup: @RunWith(CdiRunner.class) public abstract class CdiUnitBaseTest extends DBUnitBaseTest { @Produces public EntityManager em() { return em; //field from base class filled @BeforeClass } @Produces public Logger logger() { return LogManager.getLogger(); } } public class SurveyBeanTest extends CdiUnitBaseTest { @Inject private SurveyBean
