这段代码是一个JUnit测试类,用于测试SmartmallCommentService类中的query方法。这个方法用于根据不同的参数查询商品评论,并返回一个评论列表。在测试中,使用了JUnit的断言方法来判断查询结果是否符合预期。setUp方法用于在测试开始前初始化测试环境,tearDown方法用于在测试结束后清理测试环境。在测试类中使用了SpringBoot的测试注解@SpringBootTest和@RunWith(SpringRunner.class)来启用Spring容器,@Transactional注解用于将测试方法放在一个事务中,以保证测试数据不污染数据库。在query方法中,先定义了一些查询参数,然后根据showType的值来判断查询类型,如果showType为0或1,则执行查询并判断查询结果是否符合预期,如果showType不为0或1,则抛出一个运行时异常。
