JMeter - Parallel plus sequential thread groups execution in the same test plan

Question

I have my jmeter test plan like this,

Test Plan
  Thread Group1
  Thread Group2
  Thread Group3
  Thread Group4

and my Test Plan Configuration is set to run all thread groups in parallel

Here I want to execute Thread Group1 and then Thread Group2 sequentially and same Thread Group3 and then Thread Group4 But Thread Group1 and Thread Group3 parallel

So is there any way to group together Thread Group1 with Thread Group2 and Thread Group3 with Thread Group4 to run sequentially?

I know this very weird requirement but I have to suffer through it, appreciated your help in advance, thanks.

Answer 1

I see 3 options here:

1. Use schedule which would allow you to schedule 4 groups in a way that Group 1 and 3 run at the same time, and Groups 2 and 4 are scheduled to run after 1 and 3 complete.

2. Run them using 2 JMeters: in one JMeter you will have Thread Group1 and Thread Group2, in the other - Thread Group3 and Thread Group4. Each JMeter will be configured to run thread groups sequentially, but both will run in parallel, thus Thread Group1 and Thread Group3 will run in parallel

3. Change test setup, so that there are 2 thread groups:

   • Thread group A combines Thread Group1 and Thread Group2
   • Thread group B combines Thread Group3 and Thread Group4

   inside Thread group A and Thread group B you can use Loop controller to achieve specific number of iterations instead of Loop on Thread Group level. I.e.:

   Thread Group A
       Loop Controller [Count = same count as was used for Thread Group1]
           all samplers of Thread Group1
       Loop Controller [Count = same count as was used for Thread Group2]
           all samplers of Thread Group2
   Thread Group B
       Loop Controller [Count = same count as was used for Thread Group3]
           all samplers of Thread Group3
       Loop Controller [Count = same count as was used for Thread Group4]
           all samplers of Thread Group4
