How to delay my each thread group in JMeter (without using startup delay)

Question

Here I have 4 Thread Groups present in my Test Plan and I have a requirement, need to run test plan in the time interval of 30 minutes between each of my Thread Group (2nd thread group should start only after 30 minutes, after the completion of 1st thread group and so on).

But cannot estimate the actual duration for all my thread groups. And my Ramp-up period should be 0 for all my thread groups, is there any solution to full fill my requirement ?

Thanks in advance

Answer 1

1. Add Test Action Sampler to the end of each Thread Group

2. Configure it as follows:

   • Target: Current Thread
   • Action: Pause
   • Duration: 1800000
3. Add a Synchronizing Timer as a child of the Test Action sampler and set Number of Simultaneous Users to Group by to be equal to number of threads in the current Thread Group

This way Test Action sampler will act as a "rendezvous point" so all threads in the current Thread Group will sleep for 1800000 milliseconds (1800 seconds == 30 minutes), this way you will get a 30 minutes delay between Thread Groups.

Answer 2

Adding to @Dmitri T answer, Make sure in Test Plan the uncheck Run Thread Groups Consecutively so it won't try to execute in parallel

You can add Critical Section Controller in each Thread Group as the parent of all other components with same name (default is global_lock)

That way no Thread Group will start until previous thread ends.

EDIT

For getting result between threads: Add to each thread group Generate Summary Results to get the result of each thread

Generates a summary of the test run so far to the log file and/or standard output.
