### 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 ###

![在这里插入图片描述][1c0d2a4cecae4567b3eaaddb9f4436c1.png]

### 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；

![在这里插入图片描述][099ba1e2a26c49e4a6d7c5b530314d47.png]

运行脚本后发现，有20个请求，因为线程数为10，循环了2次。
