What are the attributes of “Stepping Thread Group”?
a. Name: To provide Thread Group name. It may be your Test Case/Test Scenario name
b. Comments: To provide comments
c. Action to be taken after a Sampler error: Actions taken in case of sampler error occurs, either because the sample itself failed or an assertion failed etc. The possible choices are:
i. Continue - ignore the error and continue with the test
ii. Start Next Loop - ignore the error, start next loop and continue with the test
iii. Stop Thread - current thread exits
iv. Stop Test - the entire test is stopped at the end of any current samples.
v. Stop Test Now - the entire test is stopped abruptly. Any current samplers are interrupted if possible.
d. Threads Scheduling Parameters: Number of users to simulate.
1. This thread group will start M threads (Users) : Total number of users in your test scenario. These users will be distributed in ramp-up manner according to later conditions.
where M is number of users
where M is number of users
2. First Wait for X Seconds: Delay in second to start the first thread.
where X is the delay in seconds
where X is the delay in seconds
3. Then start N threads: After X delay N number of users will be started
4. Next, add O threads every P seconds using ramp-up Z seconds: After adding N threads if you user count is different then you can use this field. Such number of users will be stepped-up across the test with the given ramp-up rate (Z) at every P seconds.
4. Next, add O threads every P seconds using ramp-up Z seconds: After adding N threads if you user count is different then you can use this field. Such number of users will be stepped-up across the test with the given ramp-up rate (Z) at every P seconds.
5. Then hold load for: It represents the steady state of Work Load Scenario.
6. Finally, stop Q threads every R seconds: It represents ramp-down time.

Hi,
ReplyDeleteI have run a test using stepping thread group of 10 users and add 1 thread for very 10 second's. holding time is 600 seconds. and finally stop 1 thread every 20 seconds.
But for my case samples are around '57781'. I am seeing this sample count is Aggregate report, Summary Report and View results in Table
*I have run the same scenario twice, i got ''57781'' samples first time and '34983' sample second time*.
Please let me the the difference why the sample count is different and What is the sample count
Hi Ravi,
DeleteCould you please compare the response time of both the tests? If response time of the requests increases then you will achieve less throughput.
Even I face the same issue, fired the scenario with 5 users and VIEW RESULTS TREE shows me 20+ requests.
ReplyDeleteCan I please know the logic how Stepping Thread works?
Please give me full information. You can also send details on my emailID (Use 'Ask Your Queries' in the right pane bottom of the page)
DeleteHi can we build the any mathematical formula for Ultimate Thread Group.?
ReplyDeleteYes, you can.
DeleteHi,
ReplyDeleteMy question is- How the next 45 users will enter into the system? What is the logic behind that and are we using 10 sec(given in example) & ramp up time for that
Hi Pallawi,
DeleteFrom where you got 45 users figure?
Yes, you can consider ramp-up as 30 users in each 10 sec .
In above gif, for Thread Scheduling Parameter , 45 is given for - 'Next, add 45 threads every 10 seconds'
DeleteTotal number of user is 150.
Delete1. JMeter will wait for 10 seconds
2. Initiate 30 users with ramp-up rate 5 seconds (6 users in 1 second will ramp-up).
3. After that JMeter will wait for 30 seconds
4. Add 45 users with the ramp-up rate 5 seconds (9 users in 1 second will ramp-up).
5. JMeter will wait for 30 seconds
6. Add more 45 users with the ramp-up rate 5 seconds (9 users in 1 second will ramp-up).
7. JMeter will wait for 30 seconds
8. Add remaining users 30 (150-30-45-45) with the ramp-up rate 5 seconds (6 users in 1 second will ramp-up).
Likewise all 150 user will ramp-up and form a step graph.
Additional:
Then all 150 users will be in steady state for next 180 seconds
thank you so much
