Question: in jmeter during run if while controller conditions are met it is stopping both the loops. is there a way in which i can only stop the inner while loop.
I don't see any Samplers which would be the children of the Loop Controller so when the While Controller ends the Loop Controller will end as well
You don't need these "Counters" as there are special variables holding the values of the current loop, they are:
${__jm__Loop Controller__idx} - for the Loop Controller
${__jm__While Controller__idx} - for the While Controller
You should be using either __jexl3() or __groovy() function in order to define your condition
Demo:
i was not intializing the while loop.

i've been trying to save the value of a counter once the execution finishes, with the idea that the next one starts with that same value. For example: I start with a counter that has 1 as value, loop it 5 times and the execution finishes with that counter having his value in 5. Then, i want that counter to start with his value in 5, how is this doable?
You can save it into a file using a suitable JSR223 Test Element like:
new File('counter.txt').text = vars.get('your-counter-variable-name-here')
where vars stands for JMeterVariables class instance, see Top 8 JMeter Java Classes You Should Be Using with Groovy article for more information on this and other JMeter API shorthands
the same for initialization, you can use __groovy() function with the following code:
${__groovy(file = new File('counter.txt'); if (file.exists()) {return file.text} else { return '0'},)}
I have a while controller that stops after running for 5 seconds.
This while controller works fine when inside it, there is one sampler or one HTTP request.
Now I want to have a loop controller inside this while controller. But now, the while controller doesn't stop after 5 seconds, and the script runs for the number specified in loop controller.
Is there any way my loop controller stop working when the while controller trigers in 5 seconds?
Here's the schematic of my test plan. I want that "search" request stops after 5 seconds (the condition inside while controller), no matter the specified number in loop controller.
PS. The code inside JSR223 Sampler1 calculates the maximum time:
max = ${__timeShift(,,PT5S,,)};
vars.putObject("max", max);
And this is the logic inside While Controller:
${__groovy( now = ${__time()}; max = vars.get("max") as long; now <= max,)}
Why would you need the Loop Controller if While Controller generates loops itself?
Don't inline JMeter Functions or Variables into JSR223 Test Elements or __groovy() function otherwise you might get unexpected behaviour.
If you want to limit While Controller's number of loops to some specific maximum value just include it into your condition clause.
In the JSR223 Sampler:
max = System.currentTimeMillis() + 5000L
In the While Controller:
${__groovy( now = System.currentTimeMillis(); max = vars.getObject("max"); now <= max && (vars.get('__jm__While Controller__idx') as int) < 10,)}

I have a scenario where I need to loop for all the numbers from 0000 to 9999, and once reached status code 200, to exit the loop.
My script looks like:
If I put the static number into Loop controller works fine
But: How to lead Loop controller based on the counter element && exit the loop once status code 200 is being reached?
You can do this on one shot using While Controller and the following __groovy() function:
${__groovy(vars.put('counter'\, new java.text.DecimalFormat('0000').format(Double.parseDouble(vars.get('__jm__While Controller__idx') ?: 0))); vars.get('counter') != '0005' && ctx.getPreviousResult().getResponseCode() != '200',)}
No other test elements/loops/whatever are required
Option 1
You can exist a loop control when a condition is satisfied with an If controller and a Flow Control Action.
Set following in the IF controller
${JMeterThread.last_sample_ok}
2. Set Break Current Loop in the Flow Control Action
Note: You shall add a delay after checking the status of the last sampler. This can be achieved with a Constant Timer
Option 2
You could achieve this with a JSR223 Post-processor too.
Add a JSR223 Postprocessor to your HTTP Request
Add the following into the script window
if (vars.get("JMeterThread.last_sample_ok").toBoolean()){
ctx.setTestLogicalAction(org.apache.jmeter.threads.JMeterContext.TestLogicalAction.BREAK_CURRENT_LOOP )
}
API Documentation : Test Logical Action, JMeter Context
Option 3
Add Results Status Action Handler Postprocessor to the HTTP Request and set Break Current Loop
I have a scenario where in I need to wait for the response text .I need to send the same request till i get the required response text. I included my http samples in while loop with a counter. Now I am not able get the correct while condition.
Tried with below conditions.
${__javaScript(("${recordTypeLabel1}"!="asdf" && ${counter} < 5),)}
${__jexl3("${recordTypeLabel1}" != "asdf",)}
Both are failing. How to handle this?

The correct syntax for the __jexl3() function would be:
${__jexl3("${recordTypeLabel1}" != "asdf" && ${__jm__While Controller__idx} < 5,)}
Don't use __javascript() function as it is some form of a performance anti-pattern, stick to __jexl3() or __groovy() functions if you need to script some extra logic
Also you don't need to introduce a Counter, since JMeter 5.0 you have a special pre-defined variable called ${__jm__While Controller__idx} which holds zero-based iteration number of the While Controller. (If you change the While Controller's label to something else - make sure to amend the variable accordingly)
Exit when loop number exceeds the threshold
Exit when variable value becomes expected:
I have a BeanShell PostProcessor under the setUp Thread Group.
I put the ArrayList into the "bsh.shared" namespace like:
List personIdsList = new ArrayList();
...
bsh.shared.personIds = personIdsList;
I know how to read the value via __BeanShell function as:
${__BeanShell(bsh.shared.personIds)}
And I want to loop through this array in other Thread Group. (${personId} - it should iterating value from list)
Could you, please, tell me how to do that?
Thanks!
The easiest way would be using While Controller together with the Counter test element like:
Add While Controller to your 2nd Thread Group and put the following expression into the "Condition" area:
${__BeanShell(Integer.parseInt(vars.get("counter")) < bsh.shared.personIds.size()-1,)}
Add Counter as a child of the While Controller and configure it as follows:
Start: 0
Increment: 1
Maximum: ${__BeanShell(bsh.shared.personIds.size()-1,)}
Reference Name: counter
Refer the "current' person ID as ${__BeanShell(bsh.shared.personIds.get(Integer.parseInt(vars.get("counter"))),)}
where required
