spring boot 编写单元测试

1.开始之前

  1. 生成测试类
    快捷方式:鼠标移动到要测试的类上 按下 alt+enter
    需要的注解:
@RunWith(SpringRunner.class)
@SpringBootTest
@Test

ex:

@RunWith(SpringRunner.class)
@SpringBootTest
public class ClassServiceTest { 
  @Test
    public void addInfo()
    {
    }
}   

3.使用断言assertThat
assertThat 基本语法

assertThat( [value], [matcher statement] );

  1. Hamcrest 匹配符
    API:http://hamcrest.org/JavaHamcrest/javadoc/2.0.0.0/

5.Controller单元测试
上面只是针对Service层做测试,但是有时候需要对Controller层(API)做测试,这时候就得用到MockMvc了,你可以不必启动工程就能测试这些接口。

MockMvc实现了对Http请求的模拟,能够直接使用网络的形式,转换到Controller的调用,这样可以使得测试速度快、不依赖网络环境,而且提供了一套验证的工具,这样可以使得请求的验证统一而且很方便。

Controller类:

package com.dudu.controller;

/** 教程页面
 * Created by tengj on 2017/3/13.
 */
@Controller
@RequestMapping("/learn")
public class LearnController  extends AbstractController{
    @Autowired
    private LearnService learnService;
    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @RequestMapping("")
    public String learn(Model model){
        model.addAttribute("ctx", getContextPath()+"/");
        return "learn-resource";
    }

    /**
     * 查询教程列表
     * @param page
     * @return
     */
    @RequestMapping(value = "/queryLeanList",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject queryLearnList(Page<LeanQueryLeanListReq> page){
        List<LearnResource> learnList=learnService.queryLearnResouceList(page);
        PageInfo<LearnResource> pageInfo =new PageInfo<LearnResource>(learnList);
        return AjaxObject.ok().put("page", pageInfo);
    }

    /**
     * 新添教程
     * @param learn
     */
    @RequestMapping(value = "/add",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject addLearn(@RequestBody LearnResource learn){
        learnService.save(learn);
        return AjaxObject.ok();
    }

    /**
     * 修改教程
     * @param learn
     */
    @RequestMapping(value = "/update",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject updateLearn(@RequestBody LearnResource learn){
        learnService.updateNotNull(learn);
        return AjaxObject.ok();
    }

    /**
     * 删除教程
     * @param ids
     */@Test
@Transactional
public void add(){
    LearnResource bean = new LearnResource();
    bean.setAuthor("测试回滚");
    bean.setTitle("回滚用例");
    bean.setUrl("http://tengj.top");
    learnService.save(bean);
}
    @RequestMapping(value="/delete",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject deleteLearn(@RequestBody Long[] ids){
        learnService.deleteBatch(ids);
        return AjaxObject.ok();
    }

    /**
     * 获取教程
     * @param id
     */
    @RequestMapping(value="/resource/{id}",method = RequestMethod.GET)
    @ResponseBody
    public LearnResource qryLearn(@PathVariable(value = "id") Long id){
       LearnResource lean= learnService.selectByKey(id);
        return lean;
    }
}

6.单元测试回滚

单元个测试的时候如果不想造成垃圾数据,可以开启事物功能,记在方法或者类头部添加@Transactional注解即可,如下:

@Test
@Transactional
public void add(){
    LearnResource bean = new LearnResource();
    bean.setAuthor("测试回滚");
    bean.setTitle("回滚用例");
    bean.setUrl("http://tengj.top");
    learnService.save(bean);
}
