A cheatsheet for those who started off with RSpec expectations and mocks, and now need to translate that to Minitest.
A walk through my current learning workflow before diving into the thinking and frameworks behind it.
a.k.a. well duh, of course a Struct returns a class.
TIL about information_schema and system catalogs that you can use to query the structure of the database itself.
