本文介绍了JMeter-从命令行更改用户定义的变量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用命令行在jmeter测试计划中更新用户定义的变量 

  jmeter- n -t SimpleJmxExample.jmx -l log.jtl -Jtestproperty = 202



您可以看到我正在使用-J论据。但是，这似乎没有什么不同？是否有更好/更广泛接受的方式为测试计划传递不同的变量？



这是我的jmx文件

解决方案

嗯，用 -J 参数，您正在设置属性，并在用户定义的变量配置-变量。它将定义两个不同的实体，尽管它们具有相同的名称，但它们将具有不同的值。



根据您的情况，您可以执行以下操作。


  1. 按照上面在问题中的命令行设置jmeter属性值



    ...- Jtestproperty = 202


  2. 在UDV配置中，使用属性值来设置变量：



    testproperty = $ {__ property（testproperty ,,）}



    或



    testproperty = $ {__ P（testproperty，）}


  3. 在脚本中进一步使用 $ {testproperty} 。


同样，您也可以使用变量进行相同的操作，只需将属性称为 {__ P（testproperty，）} 即可在命令行中设置值。


I'm trying to update a "user defined variable" in a jmeter test plan using the command line

jmeter -n -t SimpleJmxExample.jmx -l log.jtl -Jtestproperty=202

as you can see I'm using the -J argument. However it doesn't seem to make any difference? Is there a better/more accepted way of passing in different variables for a test plan?

解决方案

Well, with -J argument you are setting PROPERTY, and in User Defined Variables config - VARIABLE. It will define two different entities, although having the same name, they will have different values.

In your situation you can do the following.

  1. Set jmeter property value in command-line as above in your question

    ...-Jtestproperty=202

  2. In UDV config set variable with value from property:

    testproperty = ${__property(testproperty,,)}

    or

    testproperty = ${__P(testproperty,)}

  3. Use ${testproperty} further in the script.

As well you can possibly do the same wihout using variable and simply refer property as {__P(testproperty,)} to get value set in command-line.
