How do i programmatically set parameter override sets to different test iterations for a single test case in MATLB?

For my test case, I have multiple test iterations that represent different "External Inputs." I want each test iteration to also have different "Parameter Sets." How do I dynammically assign parameter sets to specific test iterations programmatically through MATLAB.
My main goal is to have different parameter set per each test iteration. I want to save data and dynamically change the name after each test.

I also want to utilize parallel pooling to speed up modeling. How do I have N number of parallel pools running and save output data by means of a "To File" block with different file names?

Hi Matthew,
I don't support MATLAB Testing Frameworks, but I want to clarify your nomenclature, in case it helps a bit. There is only one parallel pool; however, you can have N number of workers running in that one parallel pool.
One caveat to parfor is that each of the workers sees themselves as equal identity (i.e. rank) because they don't talk to each other -- therefore they call think of themselves as rank==1. So if you want to write to a file, using the worker's rank won't help. But you could try using the workers pid, for example:
pid = feature('getpid');
filename = sprintf('results_%d',pid);
Again, I don't support Testing Frameworks so I don't know how you can fit this type of assignment into it, but programmatically, this might help.
Thanks,
Raymond

About overriding parameters programmatically, you could check the content described in this link:
