### SSM项目中单元测试的配置 ###

*  一、导入依赖
 *  二、测试(注解方式)
 *  三、测试(非注解)
 *  四、总结

# 一、导入依赖 #

<dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-test</artifactId>
          <version>5.0.3.RELEASE</version>
          <scope>test</scope>
        </dependency>
    
    
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>4.12</version>
          <scope>test</scope>
        </dependency>

# 二、测试(注解方式) #

我们为了方便，写一个测试的父类，让其他测试类继承这个父类就行，不用每次都加配置了。

package com.ssm.test;
    
    import org.junit.runner.RunWith;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    //@RunWith是JUnit的一个注解, 用来告诉JUnit不要使用内置的方式进行单元测试, 而应该使用指定的类做单元测试 对于Spring单元测试总是要使用SpringJUnit4ClassRunner.class
    @RunWith(SpringJUnit4ClassRunner.class)
    //告诉junit spring配置文件
    //如果有多个配置文件他的value是接受一个String数组 String支持通配符
    //@ContextConfiguration({"classpath:application.xml","classpath:spring-mvc.xml"})
    @ContextConfiguration(locations = { "classpath:applicationContext.xml"})
    public class TestParent{ 
    
    }

测试子类

package com.ssm.test;
    import com.ssm.dao.UserInfoDao;
    import org.junit.Test;
    import org.springframework.beans.factory.annotation.Autowired;
    
    
    public class userInfoTest extends TestParent{ 
    
        @Autowired
        UserInfoDao userInfoDao;	//数据访问层接口
        @Test
        public void testUserInfo(){ 
            System.out.println(userInfoDao.selectUserInfoById("001"));
        }
    }

测试结果

# 三、测试(非注解) #

package com.ssm.test;
    
    import com.ssm.dao.UserInfoDao;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class test1 { 
        public static void main(String[] args) { 
            ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
            UserInfoDao userInfoDao=context.getBean(UserInfoDao.class);
            System.out.println(userInfoDao.selectUserInfoById("001"));
        }
    }

测试结果

# 四、总结 #

1、@RunWith和@ContextConfiguration注解

> @RunWith就是一个运行器
> 
> @RunWith(JUnit4.class)就是指用JUnit4来运行
> 
> @RunWith(SpringJUnit4ClassRunner.class),让测试运行于Spring测试环境
> 
> @RunWith(Suite.class)的话就是一套测试集合，
> 
> @ContextConfiguration Spring整合JUnit4测试时，使用注解引入多个配置文件
> 
> 单个文件
> 
> @ContextConfiguration(Locations=“classpath：applicationContext.xml”)  
> @ContextConfiguration(classes = SimpleConfiguration.class)
> 
> 多个文件时，可用\{\}
> 
> @ContextConfiguration(locations = \{ “classpath:spring1.xml”,  
> “classpath:spring2.xml” \})
