利用junit对springMVC的Controller进行测试

http://zhangzhaoaaa.iteye.com/blog/2200096

平时对junit测试service/DAO层已经很熟悉不过了，如果不了解，可以猛戳这里http://zhangzhaoaaa.iteye.com/blog/2033355，但是我们要测试controller层，不能总重启服务器吧，（重启tomcat好慢的飘过，别。。。别走啊），那么我们就用junit4模拟请求，测试controller层的方法。

代码1：直接Controller调用方法

import static org.junit.Assert.*;  
  
import java.sql.SQLException;  
  
import org.junit.Before;  
import org.junit.Test;  
import org.junit.runner.RunWith;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.mock.web.MockHttpServletRequest;  
import org.springframework.mock.web.MockHttpServletResponse;  
import org.springframework.test.context.ContextConfiguration;  
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  
  
import com.zz.login.web.LoginController;  
  
/** 
 * @author zhzh 
 * 2015-4-7 
 */  
@RunWith(SpringJUnit4ClassRunner.class)    
@ContextConfiguration({"classpath*:/beans.xml","classpath*:/spring-mvc.xml"})    
public class TestController {  
  
    // 模拟request,response    
    private MockHttpServletRequest request;    
    private MockHttpServletResponse response;     
        
    // 注入loginController    
    @Autowired    
    private LoginController loginController ;    
        
    // 执行测试方法之前初始化模拟request,response    
    @Before      
    public void setUp(){      
        request = new MockHttpServletRequest();        
        request.setCharacterEncoding("UTF-8");        
        response = new MockHttpServletResponse();        
    }           
    /**  
     *   
     * @Title：testLogin  
     * @Description: 测试用户登录    
     */    
    @Test    
    public void testLogin() {     
        try {    
            request.setParameter("userName", "admin");  
            request.setParameter("password", "2");  
            assertEquals("login",loginController.loginIn(request,response)) ;    
        } catch (Exception e) {    
            e.printStackTrace();    
        }    
    }    
}

代码2：调用请求路径

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;  
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;  
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;  
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.webAppContextSetup;  
  
import org.junit.Before;  
import org.junit.Test;  
import org.junit.runner.RunWith;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.test.context.ContextConfiguration;  
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  
import org.springframework.test.context.transaction.TransactionConfiguration;  
import org.springframework.test.context.web.WebAppConfiguration;  
import org.springframework.test.web.servlet.MockMvc;  
import org.springframework.transaction.annotation.Transactional;  
import org.springframework.web.context.WebApplicationContext;  
  
/** 
 * @author zhzh 
 * 2015-4-7 
 */  
@RunWith(SpringJUnit4ClassRunner.class)    
@WebAppConfiguration    
@ContextConfiguration({"classpath*:/beans.xml","classpath*:/spring-mvc.xml"})   
//当然 你可以声明一个事务管理 每个单元测试都进行事务回滚 无论成功与否    
@TransactionConfiguration(defaultRollback = true)    
@Transactional   
public class TestController2 {  
    @Autowired    
    private WebApplicationContext wac;    
    
    private MockMvc mockMvc;   
      
    @Before    
    public void setup() {     
        this.mockMvc = webAppContextSetup(this.wac).build();    
    }   
      
    @Test    
    public void testLogin() throws Exception {    
        mockMvc.perform((post("/loginTest").param("userName", "admin").param("password", "1"))).andExpect(status().isOk())    
                .andDo(print());    
    }   
      
    /*@Test   
    //有些单元测试你不希望回滚   
    @Rollback(false)   
    public void testInsert() throws Exception {   
        mockMvc.perform((post("/insertTest"))).andExpect(status().isOk())   
                .andDo(print());   
    } */  
}

注意：importstatic的spring类

代码3：LoginController代码片段

/** 
     * 登录入口 
     * @param request 
     * @param response 
     * @return 
     */  
    @RequestMapping(value = "/loginTest", method = RequestMethod.POST)  
    public String loginTest(HttpServletRequest request,HttpServletResponse response){  
        String account = request.getParameter("userName");  
        String password = request.getParameter("password");  
        if (account.equals("admin")&&password.equals("1")){  
            return "index";  
        }else{  
            return "login";  
        }  
    }
