参数化变量在 csv 的 Jmeter 问题中



我测试后端应用程序，这是在NodeJS和Java技术中。 通信：WebSocket in NodeJs 部分和 HTTP in Java 部分( 在 JMeter 中，我必须参数化 URL，以便在开发 URL、生产和 prepod 之间切换。

我通过CSV文件做到了。我在拥有 Jmeter 5.0 的文件夹中创建了文件夹 CSV。我准备了 3 个 CSV 文件，我在 Jmeter 的文件夹箱中有三个 csv 文件，例如：开发.csv、生产.csv。和前奏.csv

我的 CSV 文件如下：

协议， 主机 HTTP， 10.219.227.66WS， 10.219.227.66

协议， 主机 https， prepod.myprepod.io ws， prepod.myprepod.io

协议， 主机 https， production.myproduction.io ws， production.myproduction.io

我已经在 Jmeter 中设置了：WebSocket Open Connection Serwer URL – ws 服务器名称或 IP - ${host}

CSV 数据集配置 ${__P(环境，开发(}.csv

并且此项目无法在日志中运行 我有： 原因：

出了什么问题，我必须如何改进？请帮助我

您的问题是 JMeter 在 中查找文件：

jmeter/5.0/bin/development.csv

当它在：

/

usr/local/Cellar/jmeter/5.0/bin/development.csv

因此，要使路径稳定，请使用名为 resdir 的属性，该属性将引用包含 CSV 文件的文件夹：

${__P(resdir，/usr/local/Cellar/jmeter/5.0/bin/(}/${__P(environment，development(}.csv

将 jmx 文件放在您想要的任何位置，并使用以下命令运行 jmeter bin 文件夹：

jmeter -t
