It seems that I could not import it when I tried various things Modified as follows
import json
from flagchecker import main ← here
def test_get_base_date():
myurl = "C:/Users/***/flagchecker/flagchecker/dict.json"
dict_json = json.load(open(myurl,"r"))

base_date, pre_date = main.BaseDate(dict_json).get_base_date()
assert base_date == "2021" and pre_date == "2020"
With this, the NameError has been resolved, This time, ImportError occurs ...
