I have code that depends on elapsed time (for instance: If 10 minutes has passed)
What is the best way to simulate this in pytest? Monkey patching methods in module time?
Example code (the tested code - a bit schematic but conveys the message):
current_time = datetime.datetime.utcnow()
retry_time = current_time + datetime.timedelta(minutes=10)
#time_in_db represents time extracted from DB
if time_in_db > retry_time:
#perform the retry
766
The simplest way to skip a test function is to mark it with the skip decorator which may be passed an optional reason : @pytest. mark. skip(reason="no way of currently testing this") def test_the_unknown(): ...
In pytest , mocking can replace the return value of a function within a function. This is useful for testing the desired function and replacing the return value of a nested function within that desired function we are testing.
Additionally, if you wish to display a list of fixtures for each test, try the --fixtures-per-test flag.
FreezeGun is probably the easiest solution.
Sample code from its readme:
from freezegun import freeze_time
@freeze_time("2012-01-14")
def test():
assert datetime.datetime.now() == datetime.datetime(2012, 01, 14)
