Stop JMeter test run when reaching a specific number of requests

You want to execute a JMeter performance test but you don’t want to exceed a specific number of requests , is it possible?

Yes it is 🙂

What if we can get the value of the current iteration and make a condition to stop the test when reaching a specific values. This can be done as the following

Create a basic JMeter test plan with the essential samplers and listeners

Test plan will have the following :

  1. Thread Group
  2. Http Sampler
  3. If controller
  4. Test Action Sampler
  5. Summary Report Listener

Thread Group run settings will be as the following :

Thread group settings is just an example you can use what is suitable to your test

We will put If controller and a test action as a child for it in the beginning of the test just under the Thread Group.

Everytime you call ${__counter(,)} you got the current iteration number.
in the above example we need to set a maximum of 300 requests (iterations).

“${__counter(,)}” >= 301

So why i put the condition operator to be >=301 because in case of concurrency it will be easier to check for number of iteration after you already finished your 300 iterations , give it a try if you put 300 the test will be stopped at the iteration number 299.

Test Action will be a child to the IF Controller

When the condition is true the Test Action will stop the test.

Then you have to add http request , in the example we used “”

At the end add summary report to check the number of request and run the test


With IF Controller and Test Action you can limit your test execution maximum number of requests While you executing a duration based test with multiple threads.

Generate GUID in Apache JMeter

Although there is no dedicated sampler in JMeter to generate GUIDs but you can use the built-in functions to generate them.

In this article i will share with you how to generate GUID that is unique by user and iteration and use it through your JMeter thread group or test plan.


  1. Open JMeter and add “Bean Shell Sampler”under your Thread Group

2. Add a user defined variable that will hold the GUID value , set the varible name and leve the value empty

3. Enter the following command in beanshell sampler
“vars.put(“VariableName”, “${__UUID}”);” where variable name is the name of variable created in the previous step.

4. Now we need to verify that it is working so , we will add “Debug Samper” & “View Results Tree”

5. Save , Run and check the debug sampler values in the results tree

6. now you can place the ${GUID} variable wherever you want in the thread group and it will generate a unique value for each user and each iteration (whenever the beanshell sampler executed).

*you can genrate more than one GUID everytime by pasting the line more than on time in the beanshell sampler and also add more variables in the user defined variables to hold the values.
