使用Spring配合Junit进行单元测试的总结

　最近公司的项目和自己的项目中都用到了spring集成junit进行单元测试，总结一下几种基本的用法：

　　1.直接对spring中注入的bean进行测试(以DAO为例)：

　　在测试类上添加@RunWith注解指定使用springJunit的测试运行器,@ContextConfiguration注解指定测试用的spring配置文件的位置

　　之后我们就可以注入我们需要测试的bean进行测试,Junit在运行测试之前会先解析spring的配置文件,初始化spring中配置的bean

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations={"classpath*:spring-config-test.xml"})

public class TestProjectDao {

@Autowired

ProjectDao projectDao;

@Test

public void testCreateProjectCode(){

long applyTime = System.currentTimeMillis();

Timestamp ts = new Timestamp(applyTime);

Map codeMap = projectDao.generateCode("5", "8",ts,"院内");

String projectCode = (String)codeMap.get("_project_code");

Timestamp apply_time = (Timestamp)codeMap.get("_apply_time");

System.out.print(projectCode);

System.out.print(apply_time.toString());

Assert.assertTrue(projectCode.length()==12);

}

　　2.对springMVC进行测试：

　　spring3.2之后出现了org.springframework.test.web.servlet.MockMvc 类,对springMVC单元测试进行支持

　　样例如下：

package com.jiaoyiping.baseproject;

import com.jiaoyiping.baseproject.privilege.controller.MeunController;

import com.jiaoyiping.baseproject.training.bean.Person;

import junit.framework.Assert;

import org.junit.Before;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.http.MediaType;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import org.springframework.test.context.web.WebAppConfiguration;

import org.springframework.test.web.servlet.MockMvc;

import org.springframework.test.web.servlet.ResultActions;

import org.springframework.test.web.servlet.setup.MockMvcBuilders;

import org.springframework.web.servlet.ModelAndView;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringJUnit4ClassRunner.class)

@WebAppConfiguration

//@ContextConfiguration(classes = {WebMvcConfig.class, MockDataConfig.class})

@ContextConfiguration(locations={"classpath:/spring/applicationContext.xml", "classpath*:mvc-dispatcher-servlet.xml"})

public class TestMockMvc {

@Autowired

private org.springframework.web.context.WebApplicationContext context;

MockMvc mockMvc;

@Before

public void before() {

//可以对所有的controller来进行测试

mockMvc = MockMvcBuilders.webAppContextSetup(context).build();

//仅仅对单个Controller来进行测试

// mockMvc = MockMvcBuilders.standaloneSetup(new MeunController()).build();

}

@Test

public void testGetMenu(){

try {

System.out.println("----------------------------");

ResultActions actions =

this.mockMvc.perform(get("/menu/manage.action"));

System.out.println(status());//

System.out.println(content().toString());

actions.andExpect(status().isOk());

//            actions.andExpect(content().contentType("text/html"));

System.out.println("----------------------------");

} catch (Exception e) {

e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.

}

}
