junit中test注解测试使用案列解析二

本文原创,转载请注明出处

       在上文中,已经简单的解析了junit中test注解的使用方法,今天在进行test测试时,遇到了一个异常,于是想深

入的研究一下。

       还原一下今天的异常代码:

@Service
public class UserResourceDayStatisticsServiceImpl implements UserResourceDayStatisticsService
{
    @Autowired
    private UserResourceDayStatisticsMapper dayStatisticsMapper;

    @Override
    public UserResourceDayStatistics getResourceDayStatistics(UserResourceDayStatistics dayStatistics)
    {
        try
        {
            dayStatistics =dayStatisticsMapper.getResourceDayStatistics(dayStatistics);
            System.out.println("dayStatistics"+dayStatistics);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        return dayStatistics;
    }
    @Test
    public void test(){
        try
        {
            UserResourceDayStatistics dayStatistics = new UserResourceDayStatistics();
            String userId="1234567890000";
            dayStatistics.setUserId(userId);
            System.out.println(getResourceDayStatistics(dayStatistics));
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
    
}

 在本地启动的时候,报以下错误:

       由于该测试项目部分为中间调用部分,不存在web端,测试的时候想了两种测试,一种是在本地测试,

另一种是在web前端调用后台进行测试,代码第一部分为本地测试,碰到该异常之后找了好长时间的问题,一直没有解决

,请教了大神之后,说test注解是需要在spring容器中才能加载出来,在本地测试的时候,加载不出来所需要的context,

       于是写了第二种测试,写了一个测试页面,专用调该控制类中方法,测试代码如下:

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>请求测试界面</title>
</head>
<body>
   <form action="dayStatistics/resDayStatistics" id="dayForm">
     <div>
        <input type="submit" value="input查询">
     </div>  
   </form>
</body>
<script type="text/javascript">
       function selectForm(){
         $('#dayForm').action="dayStatistics/resDayStatistics";
         $('#dayForm').submit();
        }
    </script>
</html>
View Code

在用前台调用测试的时候,调用进controller,然后就可以加载出来,然后就可以运行了
