SpringBoot Dao层接口单元测试

...

1.测试对象：SpringBoot Dao层中各方法测试。
2.测试类开始前添加的注解：
@Transactional：每个@Test测试结束后，都对数据库进行回滚，不会在数据库中留下测试数据，也有助于@Test的独立性。
@RunWith(SpringRunner.class)、@SpringBootTest是SpringBoot单元测试默认添加的注解。后续再查下这两个注解。
3.测试类中的单元测试用例举例：
测试用例名称：businessAddTest，被测试方法有addBusinessLine、getBusinessLine。程序如下。
编写思路：
1）首先定义程序中要使用的参数。
2）调用需要测试的方法addBusinessLine(BusinessLine)。
3）对该方法的结果进行判断：
Assert.assertEquals(SUCCESS, result);
注：Assert.assertEquals();及其重载方法: a. 如果两者一致, 程序继续往下运行. b. 如果两者不一致, 中断测试方法, 抛出异常信息 AssertionFailedError 。
4）调用需要测试的方法getBusinessLine(id)，对数据库的内容进行判断，判断是否插入了这条数据，也间接测试了方法getBusinessLine(id)。其实这里也可以直接对数据库进行查询，查看是否插入了这条数据。businessGet中对数据库获取到的name、creator、groupId、status分别进行判断，看是否是创建时传入的参数。

@Test
    public void businessAddTest() {
        String name = "hongtest001";
        String creator = "lihong";
        int groupId = 1;
        int status = 1;

        //增加业务线
        int id = Basic.businessAdd(name,creator,groupId,status);

        //获取业务线信息
        Basic.businessGet(id,name,creator,groupId,1);

        //增加业务线 名称重复
        BusinessLine = Basic.getBusinessLine(name,creator,groupId,status);
        SqlEnum result = BusinessLineDao.addBusinessLine(BusinessLine);
        Assert.assertEquals(DUPLICATE, result);
        System.out.println("重复增加业务线结果:"+result);

        //获取业务线信息
        Basic.businessGet(id,name,creator,groupId,1);
    }

public void businessGet(int id,String name,String creator,int groupId,int status){
        Map resultmap = BusinessLineDao.getBusinessLine(id);

        //获取某id业务线的名称、创建者，所属团队、状态
        SqlEnum result = (SqlEnum)resultmap.get("result");
        BusinessLine businessLineGet = (BusinessLine) resultmap.get("businessLine");
        String nameGet = businessLineGet.getBusinessLineName();
        String creatorGet = businessLineGet.getBusinessLineCreator();
        int groupIdGet = businessLineGet.getLinkGroupID();
        int statusGet = businessLineGet.getBusinessLineStatus();

        //判断某id业务线的名称、创建者、所属团队、状态是否正确
        Assert.assertEquals(name, nameGet);
        Assert.assertEquals(creator, creatorGet);
        Assert.assertEquals(groupId, groupIdGet);
        Assert.assertEquals(status, statusGet);
        Assert.assertEquals(SUCCESS, result);

        System.out.println("获取业务线信息结果:"+result);

    }
    public int businessAdd(String name,String creator,int groupId,int status){
        BusinessLine = getBusinessLine(name,creator,groupId,status);
        SqlEnum result = BusinessLineDao.addBusinessLine(BusinessLine);
        Assert.assertEquals(SUCCESS, result);
        System.out.println("增加业务线结果:"+result);
        Map businessMap = jdbcTemplate.queryForMap("select * from interface_business_lines where business_line_name=? and status = 1", name);
        int id =  (int)businessMap.get("id");
        System.out.println("业务线id:"+ id);
        return id;
    }

4.针对BusinessLineDao类中的每一个方法，分别写出每个方法的测试用例，即每一个方法的测试都以注解@Test开始。
5.对于重复使用的程序，可以封装成类中的方法，方便调用。这里使用到的方法都放在Basic类中。在Basic类开始前添加注解@Component，在使用的时候使用@Autowired Basic Basic来实例化。
6.添加打印，方便调试使用：System.out.println("获取业务线信息结果:"+result);
7.附代码：
