SpringBoot and JPA Testing - spring

Question

After a few days on trying to figure out my problem, I am thoroughly confused. Here is what I am doing. I am running a Spring Boot project using JPA. I have gotten the JDBCTemplate solution working for one table in a PostgreSQL database. I have tested it with no problem. Now I moved to the major portion of the project with six tables. I chose JPA as there is mostly CRUD operations.
When I build and test using SpringBoot, I am getting the below two errors for my AcceptanceCriteriaTest. I see Spring cannot initialize the Abstract which leads to believer I do not have my annotations right. The other error is I ca not find my Persistence Unit identified.
Any suggestions would be greatly appreciated.
Thanks,
Russ

Here is how I configured the table using JPA:
#Entity
#Table(name="accCriteria_tbl", schema="iaReqChanges")
#SequenceGenerator(name="AcceptCritera_SEQ_GEN", schema="iaReqChanges", sequenceName = "accCriteria_tbl_accCri_id_seq", initialValue = 1, allocationSize = 1)
public class AcceptanceCriteria implements Serializable{
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator="AcceptCritera_SEQ_GEN")
#Column(name="accCri_id", updatable = false)
private Long accCri_id;
Now I want to test my Entity. This is my test case:
#RunWith(SpringRunner.class)
#PropertySource(name="X", value={"classpath:/applicationConfig.properties"})
#SpringBootTest(classes = ApplicationConfig.class)
public class AcceptCriteriaTest extends AbstractJPATest {
#Test
public void testCreateAcceptCriteria(){
String accCriteriaAction="Give Mary a little Lamb";
String accCriteriaControl="Mary's lamb must be white as snow";
String accAcceptanceCriteria="Does Mary have a little lamb. IS is white as snow?";
String busRequirement="Mary must be happy with her lamb that is white as snow";
Timestamp lastModified = new java.sql.Timestamp(Calendar.getInstance().getTime().getTime());
AcceptanceCriteria acceptCriteria = new AcceptanceCriteria();
acceptCriteria.setAccAccptCriteria(accAcceptanceCriteria);
acceptCriteria.setAccAction(accCriteriaAction);
acceptCriteria.setBusRequirement(busRequirement);
acceptCriteria.setLastModified(lastModified);
AbstractJPATest.entityManager.persist(acceptCriteria);
AcceptanceCriteria acceptCriteria2 = AbstractJPATest.entityManager.find(AcceptanceCriteria.class, acceptCriteria);
assertTrue((acceptCriteria.getAccAction().equals(accCriteriaAction)));
}
This is my Abstract Class:
public abstract class AbstractJPATest extends TestCase {
static final EntityManagerFactory EMF = Persistence.createEntityManagerFactory("jpaReqChgPU");
//#PersistenceContext
//protected static EntityManager em = null;
#PersistenceContext
protected static TestEntityManager entityManager = new TestEntityManager(EMF);
This is my ApplicationConfig class:
