Sometimes I want to test a bug by reusing a new plain profile, without pre-changing settings of the profile before running mozreg. Example: when I want to test rendering bugs with e10s enabled/disabled, I need to change the pref about e10s and restart ("retry") the build to test. So there is no interest to specify a path to a new custom profile just created for that. Is it possible to add an attribute to ask Mozreg to start with a new profile which will be reused during the run (according to the pref --profile-persistence)? NB: ofc, this profile will be deleted (or "lost" in /temp) after the run or if the user exits mozreg.
If I understand well, what you want is: > mozregression --profile-persistence=reuse # or clone-first, would be equivalent here without specifying any --profile. This will create an empty profile and it will be reused during the run, then finally deleted at the end. One other option would be to do > mozregression --profile-persistence=reuse --profile=/path/that/do/not/exists Same thing, but this time the profile won't be deleted at the end. Tell me if that help, or if I am misunderstanding.
Yes, without specifying --profile, just a standard new profile reused during the run.
Ok, then it should already works - closing this as invalid (please reopen/open a new one in case of issue).
