Does anyone have attempted to write a script in JMeter using JCIFS to write/read/delete file on a remote share? Thanks.
Extensibility is the main feature of JMeter.
In regards to your question I would recommend the following:
Download jcifs-*.jar and drop it to the /lib folder of your JMeter installation
Download groovy-all-*.jar and put it to the same location
Restart Jmeter
Add JSR223 Sampler and put JCIFS-specific code there. See JCIFS API documentation for classes and methods reference.
Make sure that "groovy" language is selected in the "Language" drop-down
Add more JSR223 Samplers if needed
Remember the following:
don't refer JMeter Variables as ${VAR} in groovy code
if you use "Script" input rather than path to groovy file - put something unique (per sampler) into the "Compilation Cache Key" input
For detailed explanation of "why groovy", groovy scripting engine installation instructions and scripting best practices see Beanshell vs JSR223 vs Java JMeter Scripting: The Performance-Off You've Been Waiting For! guide.

I am trying to clear cookies after each iteration in Taurus yaml.
I tried the solution from below thread but it didn't work:
[Google Group] https://groups.google.com/g/codename-taurus/c/wa4xIbxkUYI?pli=1
Above thread says:
For reference I did it like this:
modifications:
set-prop:
"Cookies>CookieManager.clearEachIteration": "true"
I have tried the same but didn't work.
Using JMeter I can clear the cookies but need the same behavior for Taurus. Any help.
What do you mean "for Taurus"? Taurus just provides YAML configuration of some of JMeter test elements. The "solution" you're referring is for running existing .jmx script using Taurus
Taurus doesn't support 100% of JMeter functionality when it comes to building test plan from config, refer the documentation to see what is supported.
If you want to use some JMeter functionality which is not supported by Taurus the options are in:
Reach out to Taurus developers via the forum you're referencing and ask them to implement the functionality you need
Implement it yourself, Taurus is an open source project
Switch to the existing .jmx script execution
Switch to JMeter and stop using Taurus as a wrapper
Use JR223 Test Elements to perform the removing of cookies, i.e. you could add a JSR223 PreProcessor to the first sampler in the Thread Group and call sampler.getCookieManager().clear() function there where sampler stands for HTTPSamplerBase
I have a selenium script written in Python, how do I run it through jmeter?
I read it from other posting that you can choose JSR223 sampler, but it really does not have in language portion, a choice of python.
You need to download jython jar and copy it to JMeter's lib folder
I don't think it's possible via JSR223 Sampler, although you can get Python language support in JSR223 test elements by putting Jython jar to the JMeter classpath you won't be able to install selenium module
So the options are in:
Use OS Process Sampler for launching your Python scripts
Convert your Python scripts into "pure" JMeter scripts by running them via JMeter's HTTP(S) Test Script Recorder, see Http proxies Selenium documentation chapter for example code
I created JMeter Test and under first "HTTP Request" I created a Beanshell listner script which works fine when using GUI but 8 out of 10 times the script totally get ignored in non-GUI mode.
I am also running these test in Gitlab CI using Docker Image "justb4/jmeter:latest" and Beanshell script also get ignored there. I don't know whats wrong there it is working fine with GUI
There is no such thing as "get ignored" in JMeter world, it either passes or fails, in case of failure you should see the relevant message(s) in the jmeter.log file
Also be aware that you should not be using Beanshell at all, starting from JMeter 3.1 you should be using JSR223 Listener and Groovy language for scripting, one of Beanshell's disadvantages is that it's being interpreted each time while Groovy scripts can be compiled and cached providing the most optimal performance. See Apache Groovy - Why and How You Should Use It article for more details.
Also be informed that we cannot efficiently help without seeing your code and the aforementioned jmeter.log file.
I have started leaning JMeter. So, this one tutorial asked to save the Bean Shell Assertion. On trying to save it, I am getting Access Denied error.
Your user has not right to write in this folder.
Change to your user's Documents folder
In order to be able to save file under the Program Files folder you need to be an Administrator of your machine.
Another option is running JMeter as an Administrator:
Or alternatively you can grant to your user account Full control rights onto JMeter folder:
In general overall quality of the guide can be a big question mark as:
Assertion will not be executed if there is no Sampler
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting as:
Groovy scripts can be compiled and cached - it greatly improves script performance
Groovy engine is faster than Beanshell per se
Groovy is more "modern" language and it supports all underlying Java features while in Beanshell you're stuck at Java 5 language level and cannot use generics, streams, lambdas, etc.
On top of this Groovy has a lot of enhancements, for instance built-in JSON support
If above points are enough to convince you - check out Scripting JMeter Assertions in Groovy - A Tutorial article.
please, advice how to how to execute linux bash shell command/script through BeanShell. The idea behind is to use this approach for setUp and teardown without taking place in final reports.
The goal is to setUp/tearDown test environment for each ThreadGroup
Thanks in advance
I would recommend considering switching to JSR223 Test Elements as:
Well-behaved groovy can be compiled into bytecode
Executing commands in Groovy is much easier, all you need is to add .execute() after the command and that's it
"date".execute()
"date".execute().text
Demo:
See Beanshell vs JSR223 vs Java JMeter Scripting: The Performance-Off You've Been Waiting For! article for more detailed information on Groovy scripting in JMeter.
As Beanshell is Java (scripting lang), you can use below statement in Beanshell to run a specific command.
Runtime.getRuntime().exec(command)
