The actual order of reported passed tests differs from the expected one.
This is due to pytest-dev/pytest#5196: Tests are now ordered by definition order in more cases.

I think there is no point to check the behavior of duplicated tests functions and I can only assume that originally this was a typo. In my opinion - there are 2 solutions - removal of the first duplicated test_fast function or renaming it and syncing all affected tests' assumptions.
