You're misunderstanding the intent of PEP 8, which was never supposed
to dogmatically enforce a naming standard on all Python projects
everywhere. You're also vastly overstating the impact of a minor naming
convention choice. Calling this a "large black mark" smacks of
scare-mongering to me.

Each of the third-party testing frameworks that have cropped up in this
thread extends unittest in some incompatible way. If you use any of
these extensions, it means that your unit test suite is tied to that
particular test framework. If you have an existing suite of unit tests
that you can't or don't want to convert, I'm afraid that Pry is indeed
not for you. Pry is not intended to be a general engine for running
tests written for other frameworks.
I should also note that converting from unittest to Pry is quite simple
- Pry's test structure is a superset of unittest's, and AutoTree was
explicitly written to make "unittest-style" testing possible, meaning
that no _structural_ change is needed for conversion. The most onerous
part is converting to assertion-based testing, something that will
improve the clarity and readability of your tests anyway.
