整合Junit4

第一步：引入Spring相关针对测试依赖

spring-test-5.2.6.RELEASE.jar
hamcrest-core-1.3.jar
junit-4.13.1.jar

第二步：创建测试类，使用注解方式完成：

@Test 使用 import org.junit.Test;

import com.spring5.service.TransferService;
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) //单元测试框架 SpringJUnit4ClassRunner @ContextConfiguration在spring-test包
@ContextConfiguration("classpath:bean1.xml")//加载配置文件
public class Junit4Test {

    @Autowired
    private TransferService transferService;

    @Test
    public void test1(){
        transferService.transfer();
    }
}

整合Junit5

第一步：引入Junit5的jar包

第二步：创建测试类，使用注解方式完成

@Test 使用 org.junit.jupiter.api.Test;

import com.spring5.service.TransferService;
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("classpath:bean1.xml")
public class Junit5Test {

    @Autowired
    private TransferService transferService;

    @Test
    public void test1(){
        transferService.transfer();
    }
}

使用复合注解，代替上面两个注解

import com.spring5.service.TransferService;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.junit.jupiter.SpringJUnitConfig;

//@ExtendWith(SpringExtension.class)
//@ContextConfiguration("classpath:bean1.xml")
@SpringJUnitConfig(locations = "classpath:bean1.xml")
public class Junit5Test {

    @Autowired
    private TransferService transferService;

    @Test
    public void test1(){
        transferService.transfer();
    }
}
