They are not calculated, the actual number of samples depend on your application response time.
Looking into your scenario:
So
- if your application response time will be 1000 milliseconds - you will have around 200 executions
- if your application response time will be 500 milliseconds - you will have around 400 executions
- if your application response time will be 2000 milliseconds - you will have around 100 executions
- etc.
If you want to limit the number of executions to some specific value - go for Throughput Controller
P.S. I see 7 Listeners in your Test Plan. Be informed that Listeners should be used only for tests development and debugging, in fact listeners don't add any value and only consume resources as all the information which is displayed is available in .jtl results file. So once you're happy with your test and verified that it's doing what it is supposed to be doing:
- Disable or delete all the listeners in the test plan
Run your test in command-line non-GUI mode like:
jmeter -n -t test.jmx -l result.jtl
- Once test execution finishes you will be able to open the
result.jtl
file with the Listener of your choice or generate HTML Reporting Dashboard out of it.
