JMeter - Execution Order? - jmeter

I have a test plan configured as so -
When I execute the test plan, all 3 simple controllers are executed at the same time, even though I have 1 thread set and 1 loop...
I want it to execute samples in "XML Import" then "UI - Quick Entry" then "UI - Reprint" rather than them all being executed at the same time..
I'm sure its obvious and I'm missing something. I am confused as to why this is happening.
Thanks

You can have only one Firefox Driver Config element per Thread Group, each thread (virtual user) will kick off a separate browser instance.
JMeter executes samplers upside down (unless you have Logic Controllers specifying different behaviour). See Using Selenium with JMeter's WebDriver Sampler for more details on Selenium and JMeter integration.

I had to move the two webdrivers into their own threads, this is now working as I expected it to.

Negative Active Thread Count in JMeter

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

How do you run a Postman test multiple times in JMeter

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 not able to run the Jmeter script

I am able to record the jmeter script successfully from Mozilla.
But I am not able to run the JMeter script.
In the console, I am getting messages like thread group started and finished but
in the listeners, I am not getting any results.
Can anybody help me whats going wrong here?
Move your HTTP Request 22 /Bird/Login and 37 /Bird/Login under the Thread Group so your test would look like:
Also be aware that you can quickly and easily configure JMeter for recording using JMeter Templates feature, if you choose File -> Templates -> Recording from JMeter main menu and click "Create" - you will have a "good" Test Plan suitable for recording and replaying
You have put View Results tree as child the wrong thread group.
Due to scoping rules in JMeter, it doesn’t receive any SampleResult from the Recorded Samples you are repalying.
So move it so that it becomes a child of Test Plan and you’ll get what you want

Jmeter only runs the first thread

I'm still new to Jmeter and I'm having trouble running more than one thread in my test plan.
I'm trying to run the tests using the GUI (just to make check that they pass), but when I run the test plan, it only seems to run the first thread in the plan. Is there something I've done wrong in my test plan?
Add "View result tree" listener in your test plan level instead of adding it individually for each thread group. This will solve your issue.
Hope this helps..

Endurance testing using Jmeter

I am new to Jmeter and trying to understand what all can be achieved using Jmeter. I want to perform endurance or soak testing of a application using Jmeter, i.e. I want to run a particular script for a particluar number of users for a period of 3 hours.
What all options are available to me and what is the best availablelistener to monitor the result?
Please help. Kindly add if I am missing anything that I should know before starting with soak testing?
For setting up the numbers of users and runtime of the test you use a Thread Group. Setting the runtime is done by checking the Scheduler check-box and specifying Duration.
Of the original listeners in JMeter I have found myself most oftenly just using the plain Summary Report. But JMeter Plugins gives additional listeners which may be better, it depends on what you want to measure. The JMeter Plugins also gives additional thread groups, where you can specify e.g. an increasing load over time.
Use a Thread Group to set up your number of users and the duration of your test (using the scheduler of the Thread Group).
Then add all the samplers and logic controllers you need to perform your testing.
Next, add a Summary Report listener to get an overview of your results (min/max/average and such), and add a View Result Tree listener to get an overview of EACH step your testplan is taking. This Tree listener is great to actually see what jmeter is doing, and to debug your tesplan.
BTW: if you add a HTTP Request Defaults object, you can set your URL and options in there, and don't need to add it to each and every sampler again. Especially works like a charm if you start using regexp extractors and such.
