@HonzaCuhel thanks a lot for the tests. @tersekmatija, should we set some kind of test coverage threshold for future PRs?

BTW, I don't see check results for this PR. @HonzaCuhel are they skipped?

They weren't skipped, but for some reason, there are not visible now. So I'm linking here the results:

• the pre-commit check link
• the actual tests link

I had to set some skipping rules for HW requirements for most of the tests, since a lot of them were failing on the standard GH runners. Here are the specs of the standard GH runners, which are for free. The biggest issue is the disk size, there's only 14GB, which is just not enough for all the models and the dependencies, therefore I wasn't even able to run the unittests for image generation.

Apparently, there are also GH large runners that are only available for organizations and enterprises using the GitHub Team or GitHub Enterprise Cloud plans (link). Or we could run the tests on our device.

@tersekmatija @kozlov721 Your thoughts on running resource-intensive tests?
