Need to step down number of users in load test.

Question

How do you step down the number of virtual users in a load test? I'm using VSTS 2010 Ultimate. Thanks!

Answer 1

Hi,

You can use a goal based load pattern to step up and step down the number of virtual users. Please refer http://blogs.msdn.com/b/billbar/archive/2008/09/12/how-is-the-user-load-adjusted-for-a-load-test-with-a-goal-based-load-pattern.aspx

Thanks,

Answer 2

Goal based load pattern seems to be only based on % Processor Time. I need a continuous load pattern, say ramping up to 100 users, then ramp down to 0 users after a minute and continuing this load pattern for an hour. Thanks.

Answer 3

Have a look at this thread on using a plugin

http://blogs.msdn.com/b/edglas/archive/2006/02/06/525614.aspx

very similar to what you want

 BTW, the goal based pattern can be run against more than just the % Processor Time counter as well

Answer 4

Thanks Tim for your kindly assistance.

Hello eequemls29,

Just as Tim mentioned, there are no built-in support for this, you are required to write custom load test plug-in to have it worked.

You can also refer to the following two blogs for further information.
