Spring6.0 整合Junit4和Junit5测试

1.准备工作

(1) pom.xml文件准备

<?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"

</project>

(2) 声明bean

package com.pojo;

import java.io.Serializable;
import java.time.LocalDate;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
@Component("student") // 纳入spring管理
public class Student implements Serializable {
	/**
	 * 
	 */
	private static final long serialVersionUID = 2452135272747910083L;
	@Value("1")
	private Integer id;
    
	@Value("张三")
	private String name;
    
	@Value("男")
	private String sex;

	//private LocalDate birthday;
	
	@Value("北京")
	private String address; 
	
}

(3) applicationContext.xml

<?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">
	
	<!--扫描所有的指定包的bean类 推荐使用 -->
	<context:component-scan	base-package="com"></context:component-scan>
</beans>

2.Spring6.0整合Junit4测试

 （1）以前的写法

package com.test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.pojo.Student;

/**
 * Junit单元测试
 */
public class MyJunit4Test {
	@Test
	public void testStudent01() {
		
		ApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");
		Student student = app.getBean("student", Student.class);
		System.out.println(student);
		
	}

}

（2）采用Spring整合Junit4写法

package com.test;

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;

import com.pojo.Student;


/**
 * Spring 整合junit4测试
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SpringJunit4Test {
	
	@Autowired
    private Student student;
	
	@Test
	public void testStudent02() {
		System.out.println(student);
	}
}

3.Spring6.0整合Junit5测试

package com.test;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
//对于Junit5导入的包时
//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 com.pojo.Student;

/**
 * Spring 整合junit5测试
 */
@ExtendWith(SpringExtension.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SpringJunit5Test {
    @Autowired
    private Student student;
    
   @Test
    public void testStudent03(){
        System.out.println(student);
    }
}

注意：junit4导入的Test类对应import org.junit.Test;

           junit5导入的Test类对应import org.junit.jupiter.api.Test;
