1. pom.xml 引入JAR依赖：

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>4.3.10.RELEASE</version>
    <scope>test</scope>
</dependency>

2.编写测试用例：

@RunWith(SpringJUnit4ClassRunner.class) 注解让测试运行于Spring测试环境。

@ContextConfiguration注解加载的是Spring的配置文件。

@Test 注解放在需要测试执行的方法上。

package com.phpdragon;

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)
@ContextConfiguration(locations = "/META-INF/spring/dubbo-provider.xml")
public class AtresiaTest {

    @Test
    public void test0() {
        System.out.println("test0");
    }

    @Test
    public void test1() {
        class TestObject implements Runnable {
            public void run(){
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }

        long timeTasks = 0;
        AtresiaDemo demo = new AtresiaDemo();
        try {
            timeTasks = demo.timeTasks(4,new TestObject());
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println("timeTasks ："+ timeTasks);
    }
}
