Random Controller就比较简单了,完全随机!毫无章法. 毫无任何规律的运行. 还有一个Random order Controller,随机顺序控制器就像一个简单的控制器,它将最多执行一次子元素,但节点的执行顺序是随机的. 看Demo:…

In Unity scripting, there are a number of event functions that get executed in a predetermined order as a script executes. This execution order is described below: Editor Reset: Reset is called to initialize the script’s properties when it is first a…

Jmeter之逻辑控制器(Logic Controller) 前言: 1. Jmeter官网对逻辑控制器的解释是:“Logic Controllers determine the order in which Samplers are processed.”.意思是说,逻辑控制器可以控制采样器(samplers)的执行顺序.由此可知,控制器需要和采样器一起使用,否则控制器就没有什么意义了.放在控制器下面的所有的采样器都会当做一个整体,执行时也会一起被执行. 2.JMeter中的Logic Con…
