  </code></pre>
  
  <p>However the code works fine when i run my project it retrieves the data correctly(Not in unit test mode).</p>
  
  <p>Please find below my method which the unit test will be based on:</p>
  
  <pre><code>@PersistenceContext
  private EntityManager entityManager;
  @SuppressWarnings("unchecked")
  public boolean getPersonByUserNamePassword(String firsName, String password) {
  
      String hql = "from Person p where p.firstName = :firsName and p.password =:password";
      Session mysession = entityManager.unwrap(Session.class);
  
      Query query = mysession.createQuery(hql);
      query.setParameter("firsName", firsName);
      query.setParameter("password", password);
      List&lt;Person&gt; results = query.list();
  
      if (results != null &amp;&amp; results.size() &gt; 0) {
  
          return true;
      }
      return false;
  
  }
  </code></pre>
  
  <p>My unit test below:</p>
  
  <pre><code>@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class })
  @RunWith(SpringJUnit4ClassRunner.class)
  
  @ContextConfiguration(locations = { "classpath:/Intcontext.xml" })
  
  public class PersonDaoTest {
  
      @Autowired
      PersonDao personDao;
  
      @Transactional
      @Test
      public void getPersonByUserNamePassword_Exist() {
  
          String firsName = "Andy";
          String password = "123";
  
          boolean isUserExists = personDao.getPersonByUserNamePassword(firsName,
                  password);
  
          Assert.assertTrue(isUserExists);
      }
  
  }
  </code></pre>
  
  <p>Any ideas why i am getting No transactional EntityManager available error please?:(</p>
  
  <p>thanks in advance.</p>
