JMeter笔记 | JMeter场景设计和设置

1 场景设计

1.1 什么是场景?

用来真实模拟用户操作的工作单元;

场景设计源自于用户真实操作。

1.2 设计原则

JMeter场景设计通过线程组设置来完成,有些复杂场景需要配合逻辑控制器完成;

原则是忠于用户实际操作,组合用户的各种操作到场景中来。

2 场景设置

线程组实际是建立一个线程池,对线程池进行初始化,运行时做各种异常处理。

2.4 调度器

3 实例说明

获取token接口,线程数10,时间为5秒,则每秒启动2个;

循环次数设置2;

其他默认;

运行脚本;

运行脚本后发现,有20个请求,因为线程数为10,循环了2次。
