Test and Code   /     Mocking in Python with unittest.mock - Michael Foord

This episode is a replay of a 2021 interview I did with Michael Foord.
We lost Michael in January, and I'd like to revisit this interview as a tribute. 

Michael Foord was a pivotal figure in the Python community and the creator of the mock library that's now unittest.mock. 
But he did so much more as well. 
His contributions continue to resonate within the developer community. 
This interview is just a small peek at his influence.
