Of course, a maintainer of pytest would see things in this way.
Just to add on the opposite side my experience with rewriting
rather large QA tests from pytest to the standard unittest.
Aside from our strong prejudice in favor of using just standard
library, there is my problem with py.test fixtures. They seem to
have some similar qualities to Perl ... they could be very very
mighty servant, but they could be also a very dangerous master.
The author of those tests fallen in love so much with py.test
fixtures, that he created completely undebuggable mess, with
variables jumping seemingly out of nowhere. Instead of
deciphering all that monstrosity, it was just more simple to
port all those tests to unittests, and the result is a way more
simple and readable. That is not completely fault of py.test,
the code was really horrible, but I would strongly warn py.test
users before falling completely head over the heels for the
