Service层的单元测试

一 代码位置

https://gitee.com/cakin24/code/tree/master/07/UnitTestDemo

二 关键代码

package com.example.demo.service;

import com.example.demo.entity.User;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import static org.hamcrest.CoreMatchers.is;

//表明要在测试环境运行，底层使用的junit测试工具
@RunWith(SpringRunner.class)
// SpringJUnit支持，由此引入Spring-Test框架支持！

//启动整个spring的工程
@SpringBootTest
public class UserServiceTest {
@Autowired
private UserService userService;
    @Test
    public void getUserInfo() {
        User user = userService.getUserInfo();
        //比较实际的值和用户预期的值是否一样
        Assert.assertEquals(18,user.getAge());
        Assert.assertThat(user.getName(),is("zhonghualong"));


    }
}

三 测试

1 测试不通过，控制台输出如下

java.lang.AssertionError:
Expected: is "zhonghualong"
     but: was "zhonghua"
Expected :zhonghualong
Actual   :zhonghua
