Spring对JUnit4和junit5的支持

Junit4支持

第一步：准备工作：
引入JUnit4的依赖，Spring对JUnit支持的依赖还是：spring-test，如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.powernode</groupId>
    <artifactId>spring6-015-junit</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>

    <!--仓库-->
    <repositories>
        <!--spring里程碑版本的仓库-->
        <repository>
            <id>repository.spring.milestone</id>
            <name>Spring Milestone Repository</name>
            <url>https://repo.spring.io/milestone</url>
        </repository>
    </repositories>

    <dependencies>
        <!--spring context依赖-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>6.0.10</version>
        </dependency>
        <!--spring对junit的支持相关依赖-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>6.0.10</version>
        </dependency>
        <!--junit4依赖-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13.2</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
    </properties>

</project>

第二步：创建配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
 <!--组件扫描-->
    <context:component-scan base-package="com.powernode.spring6.service"/>

<!--开启aspect的自动代理-->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
</beans>

第三步：单元测试：

package com.powernode.spring6.test;

import com.powernode.spring6.bean.User;
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;

/**
 * @author 
 * @version 1.0
 * @className SpringJUnit4Test
 * @since 1.0
 **/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring.xml")
public class SpringJUnit4Test {

    @Autowired
    private User user;

    @Test
    public void testUser(){
        System.out.println(user.getName());
    }
}

测试就不需要一直写注释掉的那两行了，可以直接用

Junit5支持

对junit5的支持即引入junit5的依赖就可以了，将版本换成5点几就好了

    
        org.junit.jupiter
        junit-jupiter
        5.9.0
        test
    

单元测试类中，其余的没变，但是@RunWith（SpringJunit4ClassRunner.class）变成了@ExtendWith(SpringExtention.class)

@ExtendWith(SpringExtension.class)
@ContextConfiguration("classpath:spring.xml")
public class SpringJUnit5Test {

    @Autowired
    private User user;

    @Test
    public void testUser(){
        System.out.println(user.getName());
    }
}
