jmeter：如何在Java代码中为现有jmx文件设置线程数？

Question

I want to parameterize the thread count in the java code for the jmx file which is envoked.

Please tell me how to do it?

My basic aim is to start with thread count of 10 and then increase it by 10 folds in the java code using loops.

Answer 1

1. Define number of threads in .jmx file using JMeter Property via __P() function like ${__P(threads,)}

2. Depending on how you launch JMeter you can set the property value like:

   • for command line: jmeter -Jthreads=10
   • via user.properties file - add threads=10 line to it

   • programmatically via JMeterUtils class

      JMeterUtils.setProperty("threads", "10"); 

See Apache JMeter Properties Customization Guide for comprehensive information on JMeter Properties and ways of working with them.
