It is a common practice to create performance test scripts by using the JMeter GUI. For test execution, however, it would be best to use the command line mode of JMeter. Whenever you need to change a parameter, like thread number, base URL, etc., you need to go to GUI mode, make modifications, and run your test. We can’t call that a good practice. JMeter lets you pass parameters in command line mode.

How to Pass an Argument via the Command Line

A basic command line parameter is

jmeter -n -t your_script.jmx
  • -n — tells JMeter to run in non-GUI mode.
  • -t — specifies the path to source .jmx script to run.

In case you want to send parameters via command line, add the parameters below:

jmeter -n -t your_script.jmx -Jurl=www.abcdef.com -Jusername=canberk

Then you need to change your JMeter file. You can receive these parameters with a built-in function of JMeter. This function is ${__P(VariableName)}.

This way, your test scripts are going to be dynamic in terms of parametrization.

How to Pass an Argument via Loadium

When you want to run your tests in Loadium, you can use the Advanced Settings tab in Create JMeter Test. Then you can add the necessary parameters. As a result, you don’t need to re-upload your scripts everytime you change something in the jmx file.

Happy load testing…
