我已经配置了一个名为lucy_web的Django应用程序,使用pybrake将错误记录到Airbrake中。在lucy_web层次结构的模块中,我定义了一个测试函数:

import logging

logger = logging.getLogger(__name__)

def log_something():
    logger.error("Logging something...")

如果我从Django shell调用此函数,如下所示:
(venv) Kurts-MacBook-Pro-2:lucy-web kurtpeek$ python manage.py shell
Python 3.6.4 (v3.6.4:d48ecebad5, Dec 18 2017, 21:07:28)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.3.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: from lucy_web.lib.session_recommendation import *

In [2]: log_something()

我看到出现错误电子邮件:
python - 在Django测试中禁用了刹车提示?-LMLPHP
但是,如果我定义了一个测试,并尝试从那里调用它,则不会出现任何新的错误实例:
from django.test import TestCase
from django.core import mail


class SessionRecommendationTestCase(TestCase):
    def test_airbrake_notification_if_session_type_does_not_exist(self):
        from lucy_web.lib.session_recommendation import log_something
        log_something()
        import ipdb; ipdb.set_trace()

运行此操作不会导致空气制动仪表板中出现任何新的错误实例。此外,lucy_web.lib.session_recommendations为空:
(venv) Kurts-MacBook-Pro-2:lucy-web kurtpeek$ python manage.py test lucy_web.tests.test_session_recommendation.SessionRecommendationTestCase.test_airbrake_notification_if_session_type_does_not_exist

    375         from lucy_web.lib.session_recommendation import log_something
    376         log_something()
--> 377         import ipdb; ipdb.set_trace()

ipdb> mail.outbox
[]

据我从https://docs.djangoproject.com/en/2.0/topics/testing/tools/#email-services了解,在测试中,Django会将Django发送的所有电子邮件重定向到一个虚拟发件箱mail.outbox。不过,我不希望Airbrake出现这种情况,因为电子邮件可能是由它们的后端发送的——如果是这样,我也不希望mail.outbox为空。
为什么我没有收到任何空气制动测试通知?是不是更一般的事情,比如在测试期间禁用/捕获所有日志记录?

最佳答案

我通过在pybrake.Notifier'ssend_notice方法中设置一个跟踪来验证它在单元测试中没有被调用,而当我从Django shell“手动”调用函数时它却被调用。
为了获得测试覆盖率,我解决了这个问题,只是断言logger.error被调用:

from django.test import TestCase
from unittest.mock import patch

class SessionRecommendationTestCase(TestCase):
    @patch('lucy_web.lib.session_recommendation.logger.error')
    def test_create_session_from_non_existent_session_type_title_triggers_error_logging(self, mock_error):
        title = "Being Awesome"    # Title of a non-existent session type
        _create_sessions([title])
        mock_error.assert_called_with(
            f"Tried to create a session of type '{title}', but no such session type was found in the database.")

这里是我要测试的实际函数:
def _create_sessions(title_list, starting_number=1, **kwargs):
    '''Auxiliary function to create sessions from a list of SessionType titles'''
    session_number = starting_number
    for title in title_list:
        session_type = SessionType.objects.filter(title=title).first()
        if session_type:
            Session.objects.create(
                session_type=session_type,
                session_number=session_number,
                **kwargs)
            session_number += 1
        else:
            logger.error(
                f"Tried to create a session of type "
                f"'{title}', but no such session type was found in the database.")

此测试通过:
(venv) Kurts-MacBook-Pro-2:lucy-web kurtpeek$ python manage.py test lucy_web.tests.test_session_recommendation.SessionRecommendationTestCase.test_create_session_from_non_existent_session_type_title_triggers_error_logging
