I am unable to run multiple thread groups in a single test plan parallel in Jmeter.
I am using soap req in the HTTP sampler for the req using parameterise of the input values.
Please help on this.
Unchecked Run thread groups consecutively in Test Plan.
Hope this helps

We're getting negative thread count in JMeter for active threads.
The test plan contains various Http Web Test Plan related components and samplers using Parallel Controller. This is creating problems for us in getting correct metrics as JMeter is emitting the same -ve values to the listeners for active threads. Any insights what might be wrong and how to fix this?
Here's the screenshot from the test plan while executing -
First of all don't run JMeter in GUI mode, it's only for tests development and/or debugging, when it comes to test execution you should run JMeter in command-line non-GUI mode
I don't think you should have Parallel Controller as the first parent sampler, the most obvious use case is simulating AJAX requests, concurrency should be set on Thread Group level
I am trying to perform load testing for my Web Application. Have created a Test plan with 16 scenarios using a single thread group. I have added multiple sampler requests under each scenario and used throughput controllers for each of these.
But when the test is run, I noticed that the scenarios are running sequentially whereas i Want the scenarios to run in parallel.
Can someone help me with this please.
This is how JMeter works. Each thread (virtual user) starts executing Samplers upside down (or according to Logic Controllers)
When you add more threads (virtual users) there will be some concurrency, as it evidenced by __threadNum() and __time() functions output:
So just provide enough threads (virtual users) and loops (iterations) on Thread Group level and you will get the concurrency you're looking for
I have been looking into postman and JMeter for a school project and I know that you can run a postman test and get results using JMeter. I have also been told that the main reason for JMeter is that you can run that test many times in JMeter unlike postman.
Does anyone know how to do this? got any links or resources you can share or just know the answer yourself?
I have been searching online for answers and I have connected the 2 application through using the HTTP(S) Test Script Recorder but this only provides me with 1 result and I have been unable to find anything that talks about using this to run the test many times.
If anyone is able to provide me with a solution it would be much appreciated
First of all you need to convert your Postman test into a JMeter test, the approach is as simple as running test in Postman using JMeter as the proxy:
Configure JMeter for recording. The fastest way is using JMeter Templates
feature
From JMeter's main menu choose File -> Templates -> Recording and click "Create". You should get a Test Plan structure like:
Expand HTTP(S) Test Script Recorder and click "Start"
Prepare Postman for recording.
From Postman's main menu choose File -> Settings -> Proxy and configure it like:
Run your collection in Postman
JMeter should generate relevant HTTP Request samplers under the Recording Controller
Now expand Thread Group and set the desired number of threads (virtual users) and loops (iterations)
Run your test in JMeter
Inspect results using View Results Tree listener
More information: Building a Web Test Plan - Adding Users
After you record the script in JMeter, you can run multiple times in Thread Group element by (increasing Threads Number to run script with multi threads or) increasing Loop Count, if you want to just repeat the script
thread group element controls the number of threads JMeter will use to execute your test. The controls for a thread group allow you to:
Set the number of threads
Set the ramp-up period
Set the number of times to execute the test
i am having trouble with remote testing in jmeter.
my server is able to ask the client to start the test plan.
However, only the first active thread group is running, the rest of the active thread group did not run at all.
is there anything that i might have missed??
I did not tick "Run thread group consecutively"
thanks for the help, but i solved it myself. my CSV Dataset is a invalid location, making the rest of the thread group to not run at all.
i have one thread group in jmeter and in it i create several http request sampler and when i run this thread group,i found that seems all these http request executed one by one from "view rults tree". So i what to know how can all these http request run concurrently?
My thread group and test plan only need to be executed once one minute,and i use a bat file to run ,command is :
call C:\apachejmeter\bin\jmeter.bat -n -t C:\apachejmeter\app1.jmx -l d:\restmon\restmon.jtl
your prompt reply would be deeply appreciated!!!!!
This is how JMeter works:
JMeter creates threads defined in Thread Group
Threads start executing samplers upside down (default) or according to logic controllers
When there are no samplers to execute and no loops to iterate thread is being shut down
There are several ways to control concurrency:
Playing with ramp-up and run time
Using Synchronizing Timer which is capable of pausing threads until required number is reached and releases them at the same moment of time
Switching to Ultimate Thread Group which provides some extra options to control the load scenario.
I think that Synchronizing Timer is what you're looking for.
