Using unittest.mock vs pytest-mock and fixture cautions

A discussion about mocking in Python with the original contributor of unittest.mock, Michael Foord.

Of course we discuss mocking and unittest.mock. 

We also discuss:

• testing philosophy
• unit testing and what a unit is
• TDD
• where Michael's towel is, and what color

Micheal was instrumental in the building of testing tools for Python, and continues to be a pragmatic source of honest testing philosopy in a field that has a lot of contradictory information.
