I'm doing a performance test on different versions of my application.
The results end up in a csv summary-report.
Is there a way to change the variable correctly for each thread group?
Manual Script:
Script with variable: (not working, help needed).
I don't want to change the version manually when a version changes, but only one parameter. Thanks!
Try using _P or _property function in your Thread Group and Sampler names.
Like Application-${__P(version1,)}, Login-${__P(version1,)}, etc.
Provide property value via 'user.properties' file or via -J command-line argument as
jmeter -Jversion1=1.0 -Jversion2=2.0 -n -t path_to_your_script.jmx -l path_to_results.jtl
All generated reports will contain these properties.

Been struggling with this a lot lately: How do I store a custom Groovy script with imports etc in the JMeter UI so I can reuse it later?
I don't want to alter JMeter startup property files in any way
I want to be able to call this Groovy 20+ times within the JMX with different parameters
From the JMeter doc:
Once the script is working properly, it can be stored as a variable on
the Test Plan. The script variable can then be used to create the
function call.
The groovy (compatible with Beanshell) is 62 lines and includes imports of custom JAR files. If I could store this as a var callable with __groovy(param) that would be great, I don't see how to do that from the docs. Setting up 20 JSR223s is incredibly clunky but I am coming up with workarounds if there is no JMeter way to do this.

Depending on what you're trying to achieve:
There is a possibility to specify a path to the file with your code in any of JSR223 Test Elements so you won't have to copy and paste it multiple times into "Script" area so in case of changes you will need to amend it in one place only:
There is groovy.utilities property where you can specify the path to your .groovy file containing the logic callable from the __groovy() function, it defaults to bin/utility.groovy
You can compile your code to .jar file and store it under JMeter Classpath, this way you will be able to call your functions from any place. See How to Reuse Your JMeter Code with JAR Files and Save Time article for example implementation/usage details
I have many JMeter scripts that are testing different scenarios and I want to create a configuration file for some common values across my scripts, so I will not have to edit each one to change let's say the Number of Threads.
I tried the following method but without success: I created a CSV file to contain the number of threads and passed this variable inside the Thread Group.
There is no error, but the script is not starting, always showing: "Starting 0 threads for group Thread Group."
Is there a way to set the Number of Threads from an external file?
It is, you need to create a .properties file like settings.properties and define the values there for example:
number.of.threads=100
number.of.loops=10
etc.
And refer the properties in the Thread Group via __P() function:
- ${__P(number.of.threads,)}
- ${__P(number.of.loops,)}
- etc.
Once done you can pass the file to JMeter using -q command line argument:
jmeter -q settings.properties -n -t test.jmx -l result.jtl
You can also override the values from the command-line using -J command-line argument like:
jmeter -Jnumber.of.threads=10 -n -t test.jmx -l result.jtl

For me that solution it returns error when using the properties file, using the args in command line it is ok.
How does jmeter knows that the values come from that properties file?

I am facing an issue that I could not understand how to resolve.
I created a test plan that need to connect DB and count the results.
The problem is that Jmeter not perform any validation afterwards, I created a JSSR223 in the JDBC request and just want to print the results and Jmeter not print.
I created another sampler to print the DB results and still Jmeter not printing.
Jmeter just passes this steps,
In the results tree I saw that it connects to DB and failed in the assertion, but why it passes the other steps? and just moving to debug sampler?
I can not print the results, I can not perform any debug since it is just black box.
can someone please advise?
you can see in yellow all the steps that Jmeter not performed and just not exists in the results tree.

Get used to check jmeter.log file, it normally contains information regarding what went wrong, you should be able to figure out the root cause by looking into the log file. If you are not - update your question with jmeter.log file contents (at least essential parts)
My expectation is that your ${Conv_sense} variable is not defined (or cannot be cast to Integer). Double check whether it is defined or not using Debug Sampler and View Results Tree listener combination.
Also don't refer JMeter Variables like ${Conv_sense} in Groovy scripts body, use vars.get('Conv_sense}') instead, otherwise it might conflict with Groovy GStringTemplate resulting in undefined behavior.
So in the website for the plugin, the change-log for Version 0.61 (Mar 30, 2016) mentions that they have exposed Jenkins and project bindings for use in a groovy script. I'm currently trying to set a parameter (multi select) and i want it to have different options based on the value of another parameter which is set before this one in the Jenkins job. However i'm not able to get the value of that other parameter in the script.
My problem is very similar to the one explained here
I've tried using ${param}, $(param), $param, bindings.variables.get('param') in the script, and none of it works
I've also tried to set that parameter in the Variable bindings section of the script but still no success.
Any ideas about the correct way to obtain the value?
I set the variable binding as param on the other field that you want to dynamically populate and used param (please note that i didnt use $ ${} or binding.get etc). It worked for me.
As a side note, Will active choice reactive parameter work in your case?
I have a question about the printing that I perform in Jmeter, I use
System.out.println and the consul is full with data.
the problem is that if I want in each iteration to clear the consul how can I do it?
the consul is full with data from last run, or Prev thread and I just want to clear it.
regards (it is the black consul that opened in a new window.)
You should log messages using log.info("Hello World"); (log is a script global variable) instead of using OUT in your scripts. Therefore, the logs will be sent to jmeter.log file.
See the documentation about JSR223 Sampler for more information.
For Windows you can use something like:
new ProcessBuilder('cmd', '/c', 'cls').inheritIO().start().waitFor()
For other operating system it will depend on SHELL implementation, you will need to amend the command line according to your requirements, most likely using clear command.
