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。
2.1 参数说明
2.1 基本参数
2.2 在取样器错误后要执行的动作
2.3 线程属性
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。
