I know threads can be stopped by Test Action, but then I cannot see them in View Results Tree if that action was done.
I want to see results of steps before thread was interrupted/finished, Can threads be finished successfully conditionally at specific point?
P.S. workaround would be to put next steps in other if controller with negation to finish condition, however I suspect it would require significant test plan changes.
ADD: version 2.13, in 5.1 there is Break current loop and it works as I need, but I have not moved my test plan to it yet...
Test Action had name replaced to Flow Control Action
You can choose Stop to complete samplers in progress
The "Stop" action stops the thread or test after completing any samples that are in progress.
Also you have options to continue execution, but move to next iteration using
Go to next iteration of Current Loop
Or
Break Current Loop
Or
Start Next Thread Loop

No.Of Iterations in a thread Group is : 3
Thread Group Name from the below screenshot is : TCByEmployee
Thread Group performs various steps using If Controller
I want to Achieve "Loop Controller-TCbyEmployee-Login by Employees"
& "If Controller-TCbyEmployee-Login by DH" should start Next Iterations once it's completes "If Controller--TCbyEmployee-Login by PA" Iteration 1
Now the issue is : "Loop Controller-TCbyEmployee-Login by Employees"
& "If Controller-TCbyEmployee-Login by DH" continues the up to Iteration 3 before "If Controller--TCbyEmployee-Login by PA" begins
Please see the below screenshots
Your question in its current form doesn't make any sense, you need to either re-phrase it or provide minimal reproducible example
So far I can only inform you that:
Once started each JMeter thread (virtual user) starts executing Samplers upside down (or according to the Logic Controllers)
When thread executes last Sampler in the Thread Group it starts over from the beginning
If there are no more Samplers to execute or loops to iterate the Thread is being shut down.
If you're looking for a way to implement a GOTO statement - take a look at Test Fragments and Module Controller, this way you can change the flow from upside down to some custom
Also be aware that threads (virtual users) are absolutely independent and if you think that the execution order is broken might mean that another user executed another sampler at that moment
And last but not the least, don't run your test in GUI mode
objective of Flow Control Action Sampler in JMeter. what we can achieve with this Sampler during load test?
Flow Control Action sampler is used along with the logical controllers to control the sampler execution.
To pause (sleep) current or all thread for specified amount of time (duration is set in milliseconds). You could use a JMeter variable or property to set a dynamic value
To stop the current or all threads after completing the execution of samples in progress
To stop the current or all threads immediately without waiting for samples in progress to complete. Stop Now option should be selected.
To move to the next iteration
Also you can use Flow Control Action sampler to introduce a Timer in between two samplers. Please see the suggestion from official website.
Sleep for specified amount of time (for example you can implement pacing in JMeter using Flow Control Action Sampler)
Start next iteration of the current loop (for example can be applied for Loop Controller, While Controller, ForEach Controller)
Start next iteration of the Thread Group
Gracefully or immediately stop current thread or all threads (the whole test)
I'm trying to make a part of my thread group to be executed only in a last iteration of a thread. A thread will be stopped at some moment of time (by pressing stop at gui while debugging, or by sending stoptest.sh signal to the headless load stations during the load test itself), so I don't know, how many iterations will be executed to that moment. If I knew the exact number, I'd use an If controller with condition like ${__iterationNum} == 50, but that's not the case.
There is a tearDown thread group for such a thing as far as I know, but I need to access my threads local context for the operation I am executing. So basically the question can be asked as - What's the way to determine a "Stop_thread signal was allready sent, and the current iteration is the last one executed"? If i knew how to get it, I could then implement an If controller.
Hope I explained it clear enough, thanks in advance, guys
PS Jmeter 4.0
I have what I assume is a common scenario, and while I believe I have a working solution, it feels like there's probably a better way.
The issue is that I need finer granularity than the Thread Group-level Action to be taken after a Sampler error behavior. Some of my samplers represent requests that would prevent further execution of a workflow on failure. In these cases, rather than barreling ahead with subsequent requests that a real user could not make and that would fail anyway, I want the thread to move on to the next iteration loop, starting from scratch, as it were. Other samplers represent requests that would continue to be made even if some of them failed. In these cases, I want the thread to keep going.
The method I'm using now, which is clunky but seems to work, is as follows: at the Thread-Group level I have set the Action to be taken after a Sampler error to be Continue. I assume this means that by default, if a Sampler fails, the thread will continue with the next instructions until it reaches the end.
This leaves requests that I want to block/halt/restart the workflow on a failure. The solution I have found is to follow each of these Critical Actions with an If Controller:
The condition !${JMeterThread.last_sample_ok} should resolve to true if the previous Sample failed. Within the If Controller, I have a Test Action to stop execution and start the next loop iteration of the thread:
I assume Go to next loop iteration means to start the thread over, assuming the Thread Group is set up with a loop count.
This set up seems to work, in that the thread starts over at the top of the tree each time a Sampler fails and is followed by this If/Action combo. Samplers that are not followed by this block do not halt execution on a failure.
This set up also seems very clunky, and annoying, since I'm copy-pasting this failure conditional all over the place. Is there a more elegant way of getting this behavior, or have I hit upon the more-or-less right way of doing this? Thanks!
Your solution is fine except for copy/paste as you say, so the solution is to use:
Test Fragment will contain your IfController:
Module Controller will point to it:
I'm trying to run a scenario that ramps up each thread by logging them in once, loops through an business action for an hour with pacing, and logouts as it ramps down.
Ideally the threads should not log out all at once, as such it I wanted to find a way to execute a logout action for each thread ramping down.
I have tried using stepping and ultimate thread groups, however for ramp down, the threads are being stopped.
In addition, I have tried the following scenario: 1) login, 2)runtime controller scheduled for one hour with the business action, 3) logout. This however, results in premature aborts for the threads that are still executing the business action once it reaches one hour.
Any help, even implementing this in beanshell, would be greatly appreciated.
You can just use a TearDown Threadgroup. That will always be executed once your test is over.
You can use a thread group which sets a jmeter property, let's call the property "isRunning", in a pre or post processor, next that thread has a test action set to pause for the duration of the test. After the pause set the property "isRunning" to false.
When the user logs on in another thread group (your test case) grab the "isRunning" property and store the value in a jmeter variable for the thread. Once the user logs in put your business case in a while loop with the jmeter variable created using the "isRunning" property as the condtion.
Get the value of the "isRunning" property somewhere towards the end of your business case and update your jmeter variable. Put the log out controller outside of the while loop. When the first thread group sets the "isRunning" to false, the while loop in your other threads will finish executing the use case and log out when it sees that the while condition is no longer met.
If you use any type of random think timers and ramp time, the threads should essentially step down on their own, due to ramp time offsetting the start of the use case and random think times.
Not sure if this is the best way to go about this, but I needed to do the same thing you are looking for and this proved to be a feasible workaround.
