pytest-freezegun 0.4.2

Description:

pytestfreezegun 0.4.2

Wrap tests with fixtures in freeze_time

Features

Freeze time in both the test and fixtures
Access the freezer when you need it



Installation
You can install “pytest-freezegun” via pip from PyPI:
$ pip install pytest-freezegun


Usage
Freeze time by using the freezer fixture:
def test_frozen_date(freezer):
now = datetime.now()
time.sleep(1)
later = datetime.now()
assert now == later
This can then be used to move time:
def test_moving_date(freezer):
now = datetime.now()
freezer.move_to('2017-05-20')
later = datetime.now()
assert now != later
You can also pass arguments to freezegun by using the freeze_time mark:
@pytest.mark.freeze_time('2017-05-21')
def test_current_date():
assert date.today() == date(2017, 5, 21)
The freezer fixture and freeze_time mark can be used together,
and they work with other fixtures:
@pytest.fixture
def current_date():
return date.today()

@pytest.mark.freeze_time
def test_changing_date(current_date, freezer):
freezer.move_to('2017-05-20')
assert current_date == date(2017, 5, 20)
freezer.move_to('2017-05-21')
assert current_date == date(2017, 5, 21)
They can also be used in class-based tests:
class TestDate:

@pytest.mark.freeze_time
def test_changing_date(self, current_date, freezer):
freezer.move_to('2017-05-20')
assert current_date == date(2017, 5, 20)
freezer.move_to('2017-05-21')
assert current_date == date(2017, 5, 21)
