Python’s mock module (unittest.mock in Python 3.3 and higher) allows you to
observe parameters passed to functions.
I’m a little slow, so I had to dig around to figure out how to do this.
Let’s say you have a class:
Now, let’s suppose you are testing the functionality of ProductionClass, but
you want to observe the parameters passed to your internal methods but still
invoke those internal methods. I didn’t find a lot of examples of this from my
Google searches, so here is the solution using unittest.mock (or mock from
PyPI if you’re on Legacy Python 2.x):
Happy hunting.
