如果控制器使用csv输入，则使用JMeter

Question

我正在加载测试API，我正在从CSV中获取测试数据

以下是我的csv的样子

我的if控制器是这样的

但是，当我运行线程组时，我收到以下错误：

我是jmeter的新手，所以我猜这里错过了一些东西。任何帮助将不胜感激。

Answer 1

因此，在做了一些研究之后，我发现String表达式需要双引号才能使它们起作用。

因此，以下条件有效

"${CTRY}"=="USA"

Answer 2

建议在JMeter中使用Groovy language for any form of scripting，因此我建议通过__groovy() function设置If Controller条件（自JMeter 3.0起可用），相关的Groovy表达式如下： / p>

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