Arjan Codes made a video that inspired this one - ➡️ • How to Refactor Insanely Complicated Busin... - it's worth watching and he ends up with a nice design. However, the way he recommends writing tests is far too much work! Let me show you a better way.

The demo code is from this repo: ➡️ https://github.com/ArjanCodes/examples - specifically the folder 2025/logic

I'm using the tools PyCharm, PyTest and ApprovalTests.Python ➡️ https://github.com/approvals/approval...
