Spring5支持整合JUnit5

（1）整合JUnit4
第一步 引入Spring相关针对测试依赖


第二步，编写测试类

package com.daijunyi.test;
import com.daijunyi.service.AccountService;
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;
@RunWith(SpringJUnit4ClassRunner.class)//指定单元测试版本
@ContextConfiguration("classpath:bean.xml")//加载配置文件
public class JTest4 {
    @Autowired
    private AccountService accountService;
    @Test
    public void test(){
        accountService.changeMoney(1,2,10.0);
    }
}

（2）Spring5 整合JUnit5

第一步 引入 JUnit5的jar包


第二步 创建测试类

package com.daijunyi.test;
import com.daijunyi.service.AccountService;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit.jupiter.SpringExtension;
@ExtendWith(SpringExtension.class)
@ContextConfiguration(value = {"classpath:bean.xml"})
public class JTest5 {
    @Autowired
    private AccountService accountService;
    @Test
    public void test(){
        accountService.changeMoney(1,2,100.0);
    }
}

我们还可以一个复合注解@ContextConfiguration进行简化注解

package com.daijunyi.test;
import com.daijunyi.service.AccountService;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import org.springframework.test.context.junit.jupiter.SpringJUnitConfig;
//@ExtendWith(SpringExtension.class)
//@ContextConfiguration(value = {"classpath:bean.xml"})
@SpringJUnitConfig(locations = {"classpath:bean.xml"})
public class JTest5 {
    @Autowired
    private AccountService accountService;
    @Test
    public void test(){
        accountService.changeMoney(1,2,100.0);
    }
}
