Junit对Spring Controller进行单元测试

Jar包准备：junit-4.8.jar（必须是junit-4.1.0以上）

一：需要测试的方法

package com.junitDemo.controller.mobile;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class IndexController {
/**
* 主页
*/
@RequestMapping(value = "/index")
public ModelAndView index() {
LOG.info("进入了主页");
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/index");
return modelAndView;
}

}

二：测试类

在测试类中有使用到注解：

@RunWith(SpringJUnit4ClassRunner.class)

设置运行方式

@(locations={“classpath:applicationContext.xml”})
引入配置文件

package com.junitDemo.controller.mobile;

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.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml","classpath:servlet-context.xml"})
public class IndexControllerTest {

private MockMvc mockMvc;
@Autowired
private IndexController indexController;
@Before
public void setUp() throws Exception {
mockMvc = MockMvcBuilders.standaloneSetup(indexController).build();
}
/**
* 主页
*/
@Test
public void testIndex() throws Exception {
mockMvc.perform(MockMvcRequestBuilders.get("/index.html"))
.andExpect(MockMvcResultMatchers.view().name("/index"))
.andReturn();
}

}

使用andExpect()进行断言，断言方式也可以这样写：

assertEquals("/index",mvcResult.getModelAndView().getViewName());
