Paths to Parametrization - from one test to many

About this Episode

There's a cool feature of pytest called parametrization.
It's totally one of the superpowers of pytest.

It's actually a handful of features, and there are a few ways to approach it.
Parametrization is the ability to take one test, and send lots of different input datasets into the code under test, and maybe even have different output checks, all within the same test that you developed in the simple test case.

Super powerful, but something since there's a few approaches to it, a tad tricky to get the hang of.
