Some testing comments:

• Can we put the entire run_quant test in its own tests/run_quant directory?
• We should be making fixtures of any testing inputs like MODEL_ARGS, etc.. There likely will be a time where multiple different args will be accepted, so its good to make them lists and parameterize them (even if single-valued for now). This registers them in Pytest and makes it easier to see errors, rerun single failed test cases, etc.. See the models/conftest.py examples.

@BrandonGroth Typically the same dir structure as src is followed for tests, is there a specific reason that we want a new directory for a single script? Utilizing fixtures for input args is a great point, I've got a follow-up incoming PR for building docker images that has similar tests so I'll modify them all at once and create a new PR for that next week.
