Question

我有一个应用程序（使用注释的Spring 4 MVC + Hibernate 4 + MySQL + Maven集成示例），使用基于注释的配置将Spring与Hibernate集成。我有这个junit：

@Test (expected = org.hibernate.exception.GenericJDBCException.class)
    public void testInsertOrUpdateProductmiseria2() {

        List<ProductGroup> allProductGroups = productGroupDao.findAll();

        boolean test2miseria = true;

        for (ProductGroup productGroup : allProductGroups) {
            List<Productmiseria> productmiseria = miseriaDao.getmiseriaForProductGroup (productGroup.getId());

            if (productmiseria.size()==2) {


                Productmiseria miseria = new Productmiseria();
                miseria.setAdoptionDate(new Date());
                miseria.setExpirationDate(new Date());
                miseria.setCode("code");
                miseria.setProductGroup(productGroup);

                miseriaDao.saveOrUpdatemiseria(miseria);

                // can't reach this line. An exception has to be throwed by the TRIGGER TRG_miseria_ROWS  
                //ORA-20200: Product Group can not have more than 2 miserias
                test2miseria=false;

            }
        }
        Assert.isTrue(test2miseria);

    }

我也试过 @Test（expected = java.sql.BatchUpdateException.class）

但即使抛出异常，测试也未通过

ORA-06512: at "DEVICES.TRG_CRITERIA_ROWS", line 6
ORA-04088: error during execution of trigger 'DEVICES.TRG_CRITERIA_ROWS'

Answer 1

抛出的异常为java.sql.BatchUpdateException，您期待org.hibernate.exception.GenericJDBCException

Answer 2

您的测试无效，因为测试在抛出异常时停止。在这种情况下，未达到Assert.isTrue(test2miseria)。

测试方法是与任何其他方法一样执行的标准方法。例如。他们停在抛出异常的地方。唯一的区别是JUnit调用此方法，如果异常属于预期类型，则不会报告测试错误。

管理Junit中的例外情况
