Using the latest JMeter versions (v3.0 onwards)

I want to switch to version 3 of JMeter but there are a few differences and I did need to make a few changes to my setup. So far I have just tested my updated webpagetest script but I presume these changes will carry over to all up-to-date JMeter scripts.

1. Add this registry key
It is a bit odd (especially when needed on a corporate machine), but JMeter v3.0 appears to need this registry setting. Note, I am using a fairly new version of java (/cygdrive/c/Program Files/Java/jdk1.8.0_31/bin/java) here.

2. Remove the Groovy extension plugin that I needed to use in earlier versions of JMeter
JMeter v3.0 does seem to load with Groovy already available. I guess it is setup with extra extensions by design.


3. Change your runtime command for any automated test runs
In fact, on this particular example, I am still using an older version of java, but that is due to other projects that still require it. But you can see how I can set the version used on the command line anyway. This is the command I use in my Jenkins job for running webpagetest on a specific build:
"C:\Program Files\Java\jre7\bin\java.exe" -jar "C:\jmeter-3.0\bin\ApacheJMeter.jar" -n -t C:\jmeter\scripts\webpagetest-urlList-scripts-docLoaded-monitor.jmx -JurlListcsvFile=home_page2_block.csv -JtestHost=DTEnnnn.yyyyyyyyyy.local -JtestHostPort=80 -Jlocation=Office_wptdriver:Chrome.Cable -Jfail_limit=8000 -JfirstViewOnly=0 -Jruns=2 -Jitem_url=http://service.maxymiser.net/cg/v5


Printing out to the Jenkins log file (or the Jmeter console)

This is a bit more reliable than 'log.info'
(Direct java output rather than using the jmeter functions)
  System.out.println('my_ip is ' + my_ip)
