import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class) // 使用junit4进行测试
@ContextConfiguration(locations = "classpath:applicationContext.xml")//加载配置文件
public class Test1 {

}

@RunWith 用于指定junit运行环境，是junit提供给其他框架测试环境接口扩展，为了便于使用spring的依赖注spring提供了org.springframework.test.context.junit4.SpringJUnit4ClassRunner作为Junit测试环境

@ContextConfiguration(locations = "classpath:applicationContext.xml")

@ContextConfiguration(locations = { "classpath:/applicationContext1.xml", "classpath:/applicationContext2.xml" })   

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 cn.huafeng.servicetest.Car;

@RunWith(SpringJUnit4ClassRunner.class) // 使用junit4进行测试
@ContextConfiguration(locations = "classpath:applicationContext.xml")//加载配置文件
public class Test1 {

    @Autowired//spring自动注入
    Car car;

    @Test
    public void funTest(){
        System.out.println(car);
    }
}
