JMeter Beginner Tutorial 20 - How to run Scheduled + Sequential execution

Today we will learn:
HOW TO RUN A TEST FOR SPECIFIC DURATION
Thread Group - Forever - Scheduler - Duration
HOW TO RUN PERFORMANCE TEST SEQUENTIALLY
Test Plan - Run Thread Group Consecutively
HOW TO ADD WEBSITES SEQUENTIALLY TO A PERFORMANCE TEST
Thread Group - Forever - Scheduler - Duration + Startup Delay
_______________________________________________
HOW TO RUN A TEST FOR SPECIFIC DURATION
Thread Group - Forever - Scheduler - Duration
Step 1 : Thread Group - make loop count = forever
Step 2: Select Scheduler checkbox
Step 3 : Add duration (sec)
---------------------------
HOW TO RUN PERFORMANCE TEST SEQUENTIALLY
Test Plan - Run Thread Group Consecutively
Step 1 : Test Plan - select Run Thread Groups consecutively
---------------------------
HOW TO ADD WEBSITES SEQUENTIALLY TO A PERFORMANCE TEST
Thread Group - Forever - Scheduler - Duration + Startup Delay
Step 1 : Add duration (max) to first thread group - 30 sec
Step 2 : To consecutive thread groups add delay
example (for a 30 sec test plan):
1st Thread Group : delay = 0 sec | duration = max duration of the test = 30 sec
2nd Thread Group : delay = 10 sec | duration = max - delay = 30 - 10 = 20 sec
3rd Thread Group : delay = 20 sec | duration = max - delay = 30 - 20 = 10 sec

I have little problem to understand that when we use timer when we use jpgc and when we use sequential. use of all is look like similar

[@shrilavanya5373]

Awesome video Raghav!! Keep posting!! I have a scenario as follows, I have recorded a script with blazemeter. It is for opening the application, navigating to certain pages and clicking some links. It has to run for 10 users( threads). I want to execute the requests sequentially. That is, 1st request should run for 10users followed by 2nd request and so on. When I give threads as 10 in thread group and run, it is randomly running the requests. Can you pls suggest a way to achieve this...

[@RaghavPal]

Hi, Lavanya, you can put your requests in multiple thread groups in a test plan and then run the thread groups sequentially. You can also use Controller in your case.Check this - stackoverflow.com/questions/14321662/running-multiple-thread-groups-sequentially-in-jmeter stackoverflow.com/questions/43774318/how-to-run-multiple-request-sequentially-in-apache-jmeter

[@sreenivasulugali7514]

Thanks for the video. I have one quire, what is the use of start time and end time in scheduler ?

[@RaghavPal]

It is used to schedule the run at some particular later time.

[@sreenivasulugali7514]

Rajiv, I tried but I'm unable to schedule the test. I have given start and end data and time..but the test isn't starting for the schedule time

Hi Raghav, The latest version of Jmeter no longer contains the scheduler option. Instead we specify thread life time. I would like to schedule Jmeter scripts to run at a specified time. Could you please tell me how can i do that?

Sir can you please let me know a real time implementation of Jmeter so that during interview we can justify our hands on experience

Ashok, is your query related to this video or generic. Please elaborate your question.

[@ashokverma4814]

Its not a related to video but I would like to know why use http URL rewritter (session I'd ) but same work for regular expression .

[@zalakbarot141]

Hello... Thanks for these videos. There is one doubt I have. When we create a test plan for sequential execution, after added 2thread groups. Both having duration 10-10secs. Then total run time should be 20 or each thread should be run for 10-10 secs. Because suppose 1st thread had duration 36-44 and 2nd had 48-58. And the total duration of my test plan is 25sec. But 1st thread had taken 8sec. And the delay between 1st and 2nd is 4sec. (Note: I had not added any delay between 2 threads in my test plan)

[@RaghavPal]

Hi Zalak, It also depends on the response time from the server. The request will be sent as per your settings of thread and time but will have to wait for server response too

[@zalakbarot141]

@@RaghavPal Ohk, thanks for the quick response.

[@rakhirahman4069]

Under what scenario you would apply Sequential approach?

[@RaghavPal]

Rakhi, it generally depends on the requirements like if we don't want some samplers to run in parallel. Or maybe a case someone needs the setup samplers to run first and then other requests

[@neelimapatnaik4327]

Hi @Raghav, for the sequential run I have a query Let suppose My jmx scripts looks like: ThreadGroup Controller1 Http1 Http2 Controller2 Http3 Http4 Now for this jmx i want to run it for 20 Threads, But this should be run sequently always all set of 20 users. First should run for 1 user all the HTTP1,HTTP2,HTTP3,HTTP4 and then for second user and so on. While keeping threadgroup as 20. For now my script run for 2nd user, 3rd user and so on without completing for 1st user all the 4 http request. Can you suggest!!!

At 3.10 you tell that between start time and end time there are 10 seconds. However to me, from 05:29:59:648 to 05:30:06:502 there are a mere 6 sec en 854ms. The longest period in your example is between 05:29:59:648 and 05.30.08.652, which is 09.004 seconds difference. Where did I or you go wrong?

@@RaghavPal Yes same question from me as well and please clear that there are 5 threads and you have set the duration 10 sec with one sampler, now 5 users will hit the url at least once, so how will it work? Is it working like that it will stop the test in 10 secs no matter how many threads executed? And also i noticed in the timer on upper right it is showing 15 secs duration why so? please help

In JMeter 4.0 there is no option for Start Time/End time. Please suggest how I can schedule my script for some particular date and time?

Hi Deepak, in the thread group you can set the duration

[@deepakMCA2009knit]

Automation Step by Step - Raghav Pal yeah but date time was not there. that's why I asked. If it would be there, I can better schedule my job.

[@RaghavPal]

Yes Deepak, but you can still use it. Delay overrides Start Time, and Duration overrides End Time.

Hi, you are running thread group sequentially, is there a way we can run sampler in 1 thread group to run sequentially like I have get, post and delete requests, when i run test for thread =10 then in 3rd or 4th thread delete api gets failed because I'm getting id from get request, so in 3rd or 4th step delete request execute before get request due to which it tries to delete same id which it was passed in last thread and which is already deleted in last step

I wanted to try the following scenario in jmeter. I was wondering if someone could help me with this. Lets say i want to run a test with 40 users for an hour but i want it to run for the below use case: I want 10 user to ramp up in 0 seconds (start together) and run for 15 mins and keep on running. After 15 mins i want another 10 users (total user count is 20 now) to do the same (start all tog-other ) and keep on running. So in the end of this test there will be 40 users running but i want the add 10 users every 15 mins and have them run till the end of my duration. How can i achieve this in jmeter? Thanks!!
