[QA] [Wikitech-l] Migrating away from nose (was 2017-11-01 Scrum of Scrums meeting notes)

[Amir Sarabadani]

Hey,
I did the migration, here's my notes:
- If you use "assert_equal" methods, the migration is easy, there is a
library that does the most cases for you:
https://github.com/pytest-dev/nose2pytest raise assertions would be a
problem but there is not lots of them left.
 - if you use eq_ (from nosetests.tools), you can simply replace them with
assert_equal and go to step one, but when I did, it also changed "def
__eq__" to "def __assert_eqal_" causing a mess (of course it does that, it
was very stupid of me)
 - The mark system in pytest is great (pytest.mark) Take advantage of it.

I also would be happy to lend a hand in migrating specially in review, just
ping me :)

Best
