Question:
This is a python assignment from freecodecamp:
It seems that I can get the right solution when I separately test the function of my class, but when using the main() to do the overall test, it reports a lot of falses. It seems that there are some interference between different tests in test.py. Repl link: https://replit.com/@yjzhang1/boilerplate-budget-app-1#budget.py
A quick idea:
Ask on the freeCodeCamp forum! The devs there are always active and ready to help anyone and you can quickly post your problem via the code editor. Just an Idea!
