Pytest plugin providing a fixture interface for freezegun.
$ python -m pip install pytest-freezerThe fixture name is freezer. It is a freezegun.api.FrozenDateTimeFactory instance, so refer to upstream freezegun usage for the methods.
Time is frozen by default when the fixture is injected:
def test_frozen_date(freezer):
now = datetime.now()
time.sleep(1)
later = datetime.now()
assert now == laterTime can be controlled within a test by using methods on the fixture:
def test_freezer_methods(freezer):
freezer.move_to("2022-10-17")
assert datetime.now() == datetime(2022, 10, 17)
freezer.tick()
assert datetime.now() == datetime(2022, 10, 17, 0, 0, 1)
freezer.tick(delta=12)
assert datetime.now() == datetime(2022, 10, 17, 0, 0, 13)Credit to Tomasz Kontusz for the original pytest-freezegun plugin.
