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)

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 am trying to record a script for web application (https protocol)using jmeter-5.3. The xml file in the view result tree of HTTP(S) Test Script Recorder is capturing all the calls. but once I finished my recording and check the xml file doesn't have the calls(the first 3-4 transaction calls) in the beginning of the script in the xml. why its happening and how can I fix it?
According to JMeter Best Practices you should be using the latest version of JMeter so consider upgrading to JMeter 5.4.3 (or whatever is the latest version which is available at JMeter Downloads page)
Check "Grouping" setting of the HTTP(S) Test Script Recorder, it might be the case you have Store 1st sampler of each group only selected and it can discard important requests:
Make sure to use Recording Template as it generates good and valid recording test plan
Check jmeter.log file for any suspicious entries
Try alternative way of recording a JMeter test i.e. JMeter Chrome Extension and see whether all requests which should be captured are captured.
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 have a program I wrote that gets two parameters and set some files to be upload, and I want to know if I can run it from Jmeter before performing the HTTP upload requests.
You can use OS Process Sampler to invoke the .exe file of your C# program.
You can execute any program using JSR223 Sampler and Groovy language. If you don't want this execution to appear in the .jtl results file you can use i.e. JSR223 PreProcessor instead.
The relevant code will be as simple as:
"your_command".execute()
If you need the command output, you can amend it as:
"your_command".execute().text
The approach works on any operating system. See Groovy is the New Black article to learn what else could be done with Groovy.
I want to run java code in jmeter using BSF shell but it shows an error:
"Response message: org.apache.bsf.BSFException: unable to load language: java".
Please provide url where I can download java language jar for jmeter.
Easy way: switch to Beanshell Test Elements, Beanshell is quite Java-compliant (apart from modern features like generics, switch statement on strings, etc.
Hard way: patch bsf-2.4.0.jar file (lives under /lib folder of your JMeter installation) to add JavaEngine class to it.
Right way:
From BSF Sampler Documentation:
The BSF API has been largely superseded by JSR-223, which is included in Java 6 onwards. Most scripting languages now include support for JSR-223; please use the JSR223 Sampler instead. The BSF Sampler should only be needed for supporting legacy languages/test scripts.
So consider using JSR223 Test Elements and Groovy language instead. In 99% of cases valid Groovy code will be valid Java code so it's unlikely that you'll have to change anything. See Beanshell vs JSR223 vs Java JMeter Scripting: The Performance-Off You've Been Waiting For! guide for details.
