@ieivanov I think I may have introduced something here that fails one of the tests, and I guess the next step is to run locally and try to fix it. It occurs to me that it would be very helpful to have a brief README with instructions on how the system works and how to set this up. I know you've explained this to me before, but I can't remember where that was.

Happy to add some documentation on the testing. In short, on Windows you can run pytest from a console or PyCharm as usual. The testing infrastructure will download and install the latest nightly build of MM under ~/Micro-Manager-nightly if that folder doesn't exist. On macOS the automatic installation doesn't work yet, so you'll have to manually install MM in ~/Micro-Manager-nightly, e.g. /Users/ivan.ivanov/Micro-Manager-nightly. Let me know if this still doesn't work for you.

It looks to me that this PR could resolve #359, is that correct?

Thanks! I had just forgotten the Mac part, but I think that solves it for me.

Yes, I think you're right. Will continue the conversation there
