junit基础学习之-测试controller层（2）

准备工作：

eclipse本身带有junit4，可以直接build path，加入junit。

连接数据库的配置文件需要修改，之前的文件是采用properties+xml文件的形式，但是在测试的时候因为不能连接服务器，所以需要需要修改配置文件，最好是重新写一个配置文件，把需要的参数直接写出来就好了。

下面是我配置文件，重点是前面，后面就不需要了。

测试步骤：

1.加载junit类，spring配置文件，指明junit测试器，@Runwith

2.定义变量，controller类，mockHttpServletRequest类，mockHttpServletResponse类

3.初始化变量，@Before注解

4.实现测试方法，@Test注解，request.setResuestURI,request.setMethod,其他自己想测试的方法。

package swust.edu.cn.postdoctors.controller;

import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.test.web.ModelAndViewAssert;
import org.springframework.web.servlet.ModelAndView;
import junit.framework.TestCase;

@RunWith(SpringJUnit4ClassRunner.class) // 整合 
@ContextConfiguration(locations={"classpath:spring-mybatis-test.xml","classpath:spring.xml","classpath:spring-mvc.xml"}) // 加载配置 
public class UserControllerTest extends TestCase {

    private  UserController userController;

    private  MockHttpServletRequest request ;
    private  MockHttpServletResponse response ;
    
    //省略set get函数
    @Before
    public void before() throws Exception {
        userController  = new UserController();
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();
    }

    @Test
    public void testSelectUserById(){
        
        request.setRequestURI("/postDoctors/userController/selectUserByLoginNameAndPswd");
        request.setMethod("post");
       
        try{
           final ModelAndView mav = userController.selectUserByLoginNameAndPswd("smx","123" ,request, response);
           ModelAndViewAssert.assertModelAttributeAvailable(mav, "map");  
           System.out.println(" ========= " );
        }catch (Exception e){
            e.printStackTrace();
        }
    }
    
}
