问题
I have 29 Simulink/Matlab Test. It has a lot of different reference models. Before running a 20 second simulation , it has to load all reference models and create a lot of simulation artifacts in a work folder. A lot of reference model are shared in-between test.
When running one test at a time, I have no issue, all simulation artifact are created and used to run the various simulation. Everything Passes.
When running it all via parallel processing. I have a issue.Some simulation artifact are not built or missing, hence my simulation fails even before running.But surprisingly, not all 29 of them fail. It actually random,last time it was 17, another time it was 22. And it even ran once with 0 fail.
Another note, I only have this issue when running it on a self-hosted computer on Azure-Pipelines for CI purposes.
I would like to fix this issue and reproduce stable test pass/fail results of one at a time run, but on parallel process run. How would I do that?

Update:
I found that I have also another kind of error, leads pretty much to same result.

回答1:
I made a runSingleTest() that I run before my parallel run. Before running it creates all required model reference mexw64 files in the **/work/sim_artifact folder.
Hence when the parallel run they don't need to create any new files, they either use whats already there or update the files.
I have been having no issue since that change. Just a longer run time because of that repetitive test.
