тестирование приложения фляги с макетом / патчем вызывает ошибку flask_security в отношении отсутствующего файла перевода

Question

Я пытаюсь включить насмешку и исправления в тесты приложения Flask.Я использую Python 2.7, unittest в стандартной библиотеке, и я установил пакет mock;

Сейчас я пытаюсь пропатчить os.path.exists и одну из моих собственных функций.Если я исправлю свою собственную функцию, тест (который сейчас является просто assert True) выполняется.Если я попытаюсь исправить os.path.exists, например,

[определено в файле помощника и импортировано]

def mock_os_path_exists(arg):
    return True

Тогда этот тест

from flask_brain_db import db
from user.models import *

class UserTest(unittest.TestCase):
    def setUp(self):
        # <app config is here>
    def tearDown(self):
        # <teardown proc is here>

       def register(self, email, password=None):
           return self.app.post('/register', data=dict(
           email=email,
           password=password,
           password_confirm=password
           ),
           follow_redirects=True)

    def register_and_commit_user(self):
        rv = self.register('tom.higgins@mailinator.com', 'test123')
        user = User.query.filter_by(email='tom.higgins@mailinator.com').first()
        user.confirmed_at = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        db.session.commit()
        return rv

    @patch('os.path.exists')
    def test_label_view(self, mock_os_path_exists):
        self.register_and_commit_user()
        assert True

ошибкинапример, так:

Попытка найти эту ошибку в Google не приводит к появлению чего-либо значимого.Кажется, мне просто нужен файл.Я не уверен, почему исправление встроенного метода вызывает это событие, а исправление моего собственного - нет, но я бы с радостью добавил этот файл, если бы знал, где его взять.Я искал это в проекте безопасности колбы, но Я не вижу, что это там .
