在写测试类时报错，java.lang.Exception: No tests found matching Method

  public void testDelete(){
    Session session=HibernateUtil.openSession();
     Transaction tx=session.beginTransaction();
     Customer  c=   session.get(Customer.class, 13L);

        session.delete(c);
      tx.commit();
      session.close();

解决方案原因： 在public 方法前加上@Test，调用测试方法。
