@pytest.fixture(params=['period', 'comma'])
def decimal_sep_localization(self, request): (source)

Including this fixture in a test will automatically execute it with both types of decimal separator.

So:

def test_decimal(decimal_sep_localization):
    pass

is equivalent to the following two tests:

def test_decimal_period_separator():
    pass

def test_decimal_comma_separator():
    with CommaDecimalPointLocale():
        pass
