JMeter“如果控制器"带参数? [英] JMeter "if controller" with parameters?

问题描述

我正在阅读 JMeter 文档 并发现了这个信息框关于如果控制器":

I was reading the JMeter documentation and came across this info box about "If Controllers":

当条件被解释为 Javascript 时，没有变量可用于脚本.如果您需要访问此类变量，请选择将条件解释为变量表达式?"并使用 __javaScript() 函数调用.然后您可以在脚本中使用对象vars"、log"、ctx"等.

No variables are made available to the script when the condition is interpreted as Javascript. If you need access to such variables, then select "Interpret Condition as Variable Expression?" and use a __javaScript() function call. You can then use the objects "vars", "log", "ctx" etc. in the script.

我不太了解这个.这是否意味着如果我想访问用户定义的参数"，那么我只能通过编写一些 JavaScript 来访问它?此框后面的示例然后引用${COUNT}"

I don't quite follow this. Does this mean if I want access to a "User Defined Parameter" then I can access it only by writing some JavaScript? The example that follows this box then refers to "${COUNT}"

有人可以用一两个例子来阐明 If 控制器的用法吗?

Could someone clarify the usage of the If Controller, maybe with an example or two?

推荐答案

你可以简单地使用类似

${my_variable}=='1'

有时 JMeter 文档可能会令人困惑:)
