super-duper-python-imports

In this repository we are playing with python imports and inducing those pesky ImportErrors.

File Organization

project
│   README.md
│   main.py   
│
└───animals
│   │   __init.py__
│   │   animal.py
│   │   test_animal.py
│   │   mammal.py
│   │   test_mammal.py
│   │
│   └───canines
│       │   __init__.py
│       │   dog.py
│       │   test_dog.py

Dog is in the canine folder, and inherits from Mammal in the previous folder, which inherits from Animal in that same folder.

If you try to run py dog.py file directly from .\animals\canines, you will get an ImportError. If you run py main.py from the top level folder, it will happily allow these imports to work.

Lastly, if you run:

> py -m unittest

from the top level folder, with these naming conventions (NOTE: the test files are called test_class_name.py, which allows unittest to discover them) you'll get the results that you really, really want. 🥳
