测试类

@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations="classpath*:spring-config.xml") 
@TransactionConfiguration(defaultRollback=true,transactionManager="txManager")
@Transactional
public class JobSeekerServiceTest extends AbstractTransactionalJUnit4SpringContextTests{

    private JobSeekerDao jobseekerDao = new JobSeekerDao();

    @Test
    public void testGetCandidateForEmail(){
        JobSeeker result = new JobSeeker();
        JobSeeker expected = new JobSeeker();
        expected.setName("Dummy Job seeker 1");expected.setEmail("email@yahoo.com");expected.setCity("City");expected.setPhone("04523122");

        result = jobseekerDao.getCandidateForEmail("email@yahoo.com");
        assertEquals(result, expected);
    }
}

JobSeekerDao

@SuppressWarnings("unchecked")
    @Override
    public JobSeeker getCandidateForEmail(String email) {
        LOGGER.debug("Searching the candidate after an email:"+email);
        Session session = getCurrentSession();

        List<JobSeeker> candidates = session.createQuery("from JobSeeker where email=?")
                .setParameter(0, email)
                .list();


        if (candidates.size() > 0) {
            return candidates.get(0);
        } else {
            return null;
        }
    }

为什么我收到此错误的任何想法?我是Spring,Hibernate,JUnit的新手。总之,我认为我应该这样做。或者我该怎么做这个测试课?

更新

我在某处读到导致问题是扩展AbstractTransactionalJUnit4SpringContextTests,没有它我不会再得到这个错误。

异常是让您知道测试类找不到任何合适的JDBC驱动程序。您应该将JDBC驱动程序添加到测试类路径以解决此问题
