Consider linking to `pytestify` from here

[dannysepler]

i love pytest, and did a few large scale unittest -> pytest conversions at work. hurrah!

while unittest2pytest is awesome, it was missing a few features. i was going to diff those in, but using lib2to3 felt a bit less straightforward than ast / tokenize. So i made https://github.com/dannysepler/pytestify

just curious if you would consider linking pytestify as an alternative to unittest2pytest (since the last release here was a few years ago and pytestify is under active development)

• alternatively it could be helpful just to look at pytestify and give notes!

(feel free to close if irrelevant, of course)
