Leaving to @Karolk99

[Karolk99]

I think we should remove persist? option as we don't have a use case for it. We should always have it set to true.

[LVala]

The excluded tests will be fixed as a part of another task (tests in general are going to be revisited/rewritten) as we established.

[Karolk99]

Everything is alright but we have to wait for new tests before merging to master.
