How to write a unit test for datetime functions

Question

I have the following function below that returns the time as 00:00:00 . How can I write a unit test to verify this works?

def get_date() -> datetime:
    return datetime.combine(datetime.today(), datetime.min.time())
print(get_date())

Answer 1

You can do two things here:

1. Convert the datetime object to a string and assert against it:

    assertEqual("00:00:00", get_date().time().isoformat())

   and If you want to assert against date:

    assertEqual(datetime.today().strftime('%Y-%m-%d'), get_date().date().isoformat())

2. Directly assert datetime objects:

    assertEqual(datetime.min.time(), get_date().time()) assertEqual(datetime.today().date(), get_date().date())
