I have a scenario in JMeter like if the transaction enters into the if loop controller, then the execution should get stop when the all the requests in the if controller gets completed.
It should not execute the calls which are outside the controller.
How to achieve this case? can somebody suggest an idea?
There are 2 options:
Add Flow Control Action sampler as the last request in the If Controller and configure it like:
Or add JSR223 Sampler as the last request in the If Controller and put the following code into "Script" area
ctx.getThread().stop()
SampleResult.setIgnore()
See Top 8 JMeter Java Classes You Should Be Using with Groovy article to learn what do these ctx and SampleResult guys mean.
That's it, if thread enters the If Controller it will execute Sampler1, Sampler 2 and Sampler 3 and then stop. If thread doesn't enter the If Controller it will execute Sampler 1 and Sampler 4.

In my Test Plan , i have multiple transactions(not related). Is there a way to stop just the current transaction only on a sampler error. If I use the setting to stop thread/ continue next thread , it just drops the thread for each transactions, which is not very helpful for what i want to achieve. Any help please. Thanks
What do you mean by "transaction"?
"Sample error" can be caught by If Controller using ${JMeterThread.last_sample_ok} pre-defined variable as the condition and from there you can:
Add Flow Control Action sampler and use one of below 3 actions:
Or add a Module Controller pointing to a Test Fragment holding the actions which you would like to execute on Sampler's error. See Easily Write a GOTO Statement in JMeter article for more details.
I have an http request sampler1 and extracting a 'JobID' value using regular expression extractor. Now, i have http request sampler2 to check a job status in the same thread group which uses 'JobID' from previous sampler using regular expression extractor. The sampler2 has a while loop controller with condition ${__javaScript("${Status}"!="Ready",)} which is to say keep executing the sampler until status is Ready.
The issue that i am facing is, when the first sampler fails, the second sampler just takes the variable name and keeps trying and never stops because of the while loop.
the second sampler http request gets formed like:
JobID=%24%JobID%7D&request=****
Is there a way to say stop executing the second sampler when first one fails. Any input on this would be of great help.
This is how JMeter works, each thread (virtual user) executes Samplers upside down (or according to the Logic Controllers)
If you want want to execute 2nd sampler only if first one is successful you need to put your While Controller along with the 2nd sampler under the If Controller and use ${JMeterThread.last_sample_ok} as the condition
Where ${JMeterThread.last_sample_ok} is a pre-defined variable holding the result of the previous Sampler
My test plan is as follows:
Thread group
\_..other items
\_While controller (with blank condition)
\_Web socket single read sampler
\_..other items
My problem is, because I use blank condition, the While controller executes till the sampler errors out. So my question is, is there a way to filter out this last sampler? There are no other conditions I can use in the While controller as the number of times the child sampler has to be executed is not constant.
Thanks!
Add JSR223 PostProcessor as a child of the WebSocket Single Read Sampler
Put the following code into "Script" area:
if (!prev.isSuccessful()) {
prev.setIgnore()
}
In the above code prev stands for the parent SampleResult and the setIgnore() function tells JMeter to not to collect the result for the given Sampler.

I have a JMeter script running for x number of users. I want to conditionally close a user thread in a while controller. For example, if my while controller exits for a user thread, I need to stop the thread. Is it possible? Sorry if this is duplicate or a dumb question.
There are at least 2 options on how you can conditionally stop test thread or even the whole test:
Use Test Action sampler in combination with If Controller
Use Beanshell Sampler or PostProcessor and invoke setStopThread method of SampleResult class. See How to use BeanShell guide for example. For reference:
if (condition){
SampleResult.setStopThread(true); // for Beanshell Sampler
prev.setStopThread(true); // for Beanshell Post Processor
}
ctx.getThread().stop() sets the "stop" flag in the current thread, it works anywhere the JMeterContext ctx is exposed.
I have just done and verified it in a complex test script.
Suppose my threads are 30 and iteration count is 1 and I have samplers such as:
sampler1
sampler2
sampler3
....
sampler10
Whenever I run the test plan with corresponding ramp up period some of my samplers are being executed concurrently I meant user 1 is executing sampler1 and also user 20 is executing same sampler which is absolutely fine but I want sampler3 to be executed in isolation i.e. when that sampler is being executed by someone no other user should try to access it.
Is there any way?
I am using Jmeter.
Thanks in advance
As per Using the HTTP Cookie Manager guide you can put your Sampler 3 under Once Only Controller
From documentation
The Once Only Logic Controller tells JMeter to process the controller(s) inside it only once per Thread, and pass over any requests under it during further iterations through the test plan.
