spring實現單元測試

作者使用的版本爲spring 5.1.1

基類BaseTest配置單元測試環境，繼承該類的其他類可以不再配置單元測試環境
 

package Base;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;

@RunWith(SpringRunner.class)  //單元測試，SpringRunner繼承了SpringJUnit4ClassRunner類，所以用的是junit4
@ContextConfiguration("classpath:springmvc-servlet.xml")  //spring 容器配置
@WebAppConfiguration     //web環境
public class BaseTest {

}

package com.wxj233.control;

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.context.WebApplicationContext;

import Base.BaseTest;

@Rollback(true)   //事務回滾，spring默認是true，無論成功與否都會回滾
@Transactional    //事務
public class UserControlTest extends BaseTest {

	@Autowired
    private WebApplicationContext webApplicationContext;

    protected MockMvc mockMvc;
    
    @Before
    public void init() {
    	mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
	
	@Test
	public void testUserLogin() {
		try {
			String response = mockMvc.perform(MockMvcRequestBuilders.post("/user/login.do")
					.param("account", "wxj233")
					.param("password", "wxj233")).andReturn().getResponse().getContentAsString();
			System.out.println(response);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

}

另外特別提醒一下eclipse中你需要配置一下junit運行環境，右鍵測試類選Run as->Run configurations

選擇junit版本
