AttributeError: объект не имеет атрибута «monkeypatch» во время тестирования приложения pyqt5

0 голосов
/ 04 апреля 2020

У меня есть приложение PyQt5 (которое вы можете найти здесь ), и я пишу тесты для него, используя pytest.

У меня есть класс BaseTest, от которого наследуется каждый тест. Вот пример этого класса: 

@pytest.fixture(autouse=True)
    def monkeypatching(self, monkeypatch):
        self.monkeypatch = monkeypatch

Я использую его для создания обезьян, но когда я запускаю свой набор тестов:

$ pytest

Я получаю такие ошибки :

И в то же время, если я запускаю только тестовый файл, который не проходит:

$ pytest tests/func/test_save_database.py

он пройдет:

Я получаю ошибки, как это время от времени, иногда они исчезают сами по себе, но я хочу понять, почему тестирование имеет такое странное поведение и как их устранить.

Спасибо!
