利用junit对springMVC的Controller进行测试

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，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：import static 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";
    }
  }
