如果控制器带有 csv 输入，则使用 JMeter

Question

我正在对 API 进行负载测试，我从 CSV 文件中获取测试数据

这是我的 csv 的样子

我的if控制器是这样的

但是，当我运行线程组时，我得到以下错误：

我是 jmeter 的新手，所以我猜我在这里遗漏了一些东西。任何帮助将不胜感激。

Answer 1

所以，在做了一些研究之后，我发现字符串表达式需要用双引号引起来才能工作。

因此，以下条件有效

"${CTRY}"=="USA"

Answer 2

推荐使用Groovy language for any form of scripting in JMeter so I would recommend setting your If Controller condition via __groovy() function (available since JMeter 3.0), 相关的Groovy表达式是这样的:

${__groovy(vars.get('CTRY') == 'USA',)}

如果控制器带有 csv 输入，则使用 JMeter

using JMeter if controller with csv input

csv

jmeter
