For the purpose of my test, I want to create a re-usable jsr223 sampler (JSR223 Assertion) sampler, so I can just reuse it in multiple HTTP requests. What is the easiest way to achieve that using JMeter, rather than duplication of the same code?
If you place an Assertion at the same level as Samplers - it will be applied to all of them:

I have a need where executed API tests from Intellij(rest assured framework), to record into Jmeter. Is this possible at all, and if so, what is the easiest way?
Take a look at RestAssured.proxy
If you add the next line to your tests:
RestAssured.proxy("localhost",8888);
and launch JMeter's HTTP(S) Test Script Recorder - JMeter will capture the network traffic and generate relevant HTTP Request samplers and HTTP Header Managers
how to stop current iteration using jmeter and move to next iteration using beanshell script.
(Without using test action element)
I tried ctx.setRestartNextLoop(true) but this is not working.
JMeter version: 5.2.1
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for any form of scripting
If for some reason (I fail to see any valid reason though) you still want to do this using JSR223 Sampler instead of Flow Control Action sampler - the relevant code would be:
SampleResult.setIgnore()
ctx.setTestLogicalAction(org.apache.jmeter.threads.JMeterContext.TestLogicalAction.START_NEXT_ITERATION_OF_CURRENT_LOOP)

I have just started using Jmeter WebDriver Sampler for automating performance of an application. I'm curious to know that can i call one webdriver sampler from another sampler?.Is it possible in Jmeter. Because I need to login and logout in every sampler.
Theoretically it is possible via JMeter API and JSR223 bridge however it will be too complicated and in general you ain't gonna need it.
There are 2 main points which you might not know:
JMeter executes Samplers upside down so if you have the following structure:
Login Sampler
Logout Sampler
Jmeter first will execute Login than Logout. Browser instance will be shared across the samplers
There is a mechanism in JMeter which helps avoiding code duplication so if you have Logout sampler(s) somewhere in your test plan and would like to re-use it in several places instead of copying and pasting it each time you can call it using Module Controller
I need to sign my request xml and add a token to it before hitting the application. For that I am using a JSR223 preprocessor which gets the data from current sampler, makes the necessary changes and puts the data back to sampler. This approach works fine with a single thread group. When multiple thread groups are used data between the samplers(in different thread groups) gets interchanged and it results in incorrect requests for the thread group. Below is the code in my preprocessor:
import jmeter_plugin.*;
String body = sampler.getXmlData();
log.info(body);
Utils utils=new Utils();
String request=utils.getResponse( body,"url/to/fetch/token");
log.info(request);
sampler.setXmlData(request);
Tried by having a single preprocessors for the entire test plan and also separate pre processors for each thread group. Both approaches did not work.
Your approach should work fine no matter how many Thread Groups do you have. Pre-Processors are executed before each sampler in its scope and should modify only the current sampler.
Quick checklist:
Make sure you're using Groovy as JSR223 PreProcessor language
Make sure you have Cache compiled script if available box ticked
Remove these log.info lines as they create unnecessary Disk IO overhead
Make sure your Utils class don't use methods which are not Thread Safe
Looking into sampler.getXmlData() it appears you're using JMeter 3.1 or below as SOAP/XML-RPC Request has been removed in JMeter 3.2 and users are encouraged to use HTTP Request sampler instead.
If your "sign" algorithms is not very exotic if might be easier to use WS Security for SOAP JMeter Plugin which can be installed using JMeter Plugins Manager
I wrote a JMeter testplan containing hundreds of HTTP samplers/assertions. As JMeter executes each HTTP sampler, I want it to run an OS Process Sampler pre and post execution (basically call scripts to write out to remote log files on other integrated systems the start and finish points of the HTTP sampler testcase so that I know which logs correspond to which HTTP sampler executed). I don't want to have to sandwich each HTTP sampler with OS Process samplers. I was wondering if there is a way to get JMeter to execute the pre and post OS Process samplers in the background every time a HTTP sampler is run without having to explicitly add them to the testplan hierarchy. So, I currently have in the testplan tree:
Pre-OS Process Sampler (explicit)
HTTP Sampler #1
Assertions #1
Post-OS Process Sampler (explicit)
Pre-OS Process Sampler (explicit)
HTTP Sampler #2
Assertions #2
Post-OS Process Sampler (explicit)
But I want instead:
Pre-OS Process Sampler (on call in background)
Post-OS Process Sampler (on call in background)
HTTP Sampler #1
Assertions #1
HTTP Sampler #2
Assertions #2
Thanks for any guidance!

I am not sure what you are trying to do is the right method as it will negatively impact performances of the machine hosting jmeter.
I suggest you do it differently:
start a listener thread that will handle the sending of logging messages, if possible try to find a better way than process launching througj java api or webservice
use pre/post processor using jsr223 + groovy to send your messages to it
It will be much lighter
You can have a look at:

And implement your own inspiring yourself from:
