数据层的测试

数据主要使用Mybatis，因此注入的时候也只需要引入Mybatis相关的配置

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:spring/spring-dao.xml" })
public class SeckillDaoTest {// 注入Dao实现类依赖@Resourceprivate SeckillDao seckillDao;@Testpublic void testReduceNumber() {long seckillId=1000;Date date=new Date();int updateCount=seckillDao.reduceNumber(seckillId,date);System.out.println(updateCount);}
}

业务层测试

业务层会涉及到多表的操作，因此需要引入事务。而为了方便重复测试，添加回滚功能。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml" })
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
@Transactional
public class SeckillServiceImplTest {private final Logger logger = LoggerFactory.getLogger(this.getClass());@Autowiredprivate SeckillService seckillService;@Testpublic void testGetSeckillList() {List<Seckill> seckills = seckillService.getSeckillList();System.out.println(seckills);}
}

控制层测试

控制层主要模拟用户请求，这里设计到http请求，我们可以使用mock测试

@WebAppConfiguration
@ContextConfiguration({ "classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml","classpath:spring/spring-web.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
@Transactional
public class SeckillControllerTest  {@Autowiredprotected WebApplicationContext context;private MockMvc mockMvc;private String listUrl = "/seckill/list";private String detailUrl = "/seckill/{seckillId}/detail";private String expserUrl = "/seckill/{seckillId}/exposer";private long seckillId = 1000L;@Beforepublic void setUp() {this.mockMvc = webAppContextSetup(this.context).alwaysExpect(status().isOk()).alwaysDo(print()).build();}@Testpublic void testList() throws Exception {this.mockMvc.perform(get(listUrl)).andExpect(view().name("list"));}@Testpublic void testExistDetail() throws Exception {this.mockMvc.perform(get(detailUrl, seckillId)).andExpect(view().name("detail")).andExpect(model().attributeExists("seckill"));}
}
