Answer 1

I have sucess with this.

@patch('mypackage.dt')
def test_metodo(self, mock_date):
    expected = ('2018', "2018-12-14 12:34:56")
    mock_date.today.return_value = mypackage.dt(2018, 12, 14, 12, 34, 56)
    mock_date.today.return_value.strftime.side_effect = list(expected)
    self.assertIsNotNone(metodo())
    self.assertEqual(expected, metodo())
