When repeating the job they usually succeed.

Example where it failed on 1st try: https://gitlab.servus.at/aura/engine/-/jobs/6945

As discussed, I enabled test_synchronized and added a loop to increase probability of a failure.

I'm not sure if it's sufficient to do the loop inside the py files, so I modified the makefile in order to execute the target coverage multiple (e.g. 100) times...

Any news on this, can it be closed?

I tried different loop syntaxes which should work in makefiles and also worked on my local machine but for some reasons, the testcases were executed only once in the ci.

Anyhow, the tests ran very often in the past months and I also tried to trigger the error manually - I didn't notice any failure. Thus closing this ticket.
