环境

OS: Windows 10
Jmeter: apache-jmeter-4.0

背景

今天遇到一个需要借助Jmeter的测试需求，工作流程如下：

1. 发送Http请求开启后台任务
2. 循环发送Http请求检测后台任务状态，若后台任务已完成则跳出循环
3. 退出

实现思路如下：

1. 创建一个Thread Group

2. 在Thread Group中创建HTTP Request(相当于开启后台任务)

3. 使用Regular Experssion Extractor提取#2中的返回值，若状态码为200则进入下一步

4. 创建While Controller，Condition设置为LAST(在最后失败时跳循环)

5. 在While Controller中创建HTTP Request(相当于检测状态)

6. 在While Controller中创建Response Assertion，校验状态码是否为200

运行结果
