如何测试将记录作为参数的函数？

Question

我需要为文件 my_logging.py

中的函数 post_log_filter(record) 编写测试

#my_logging.py

import os
import sys
import traceback


log_format = '[%(levelname)s] %(asctime)s %(context)s %(pathname)s:%(lineno)d: %(message)s'
log_time_format = '%Y-%m-%dT%H:%M:%S%z'

def post_log_filter(record):
    # filter out undesirable logs
    logs_to_omit = [
        {'filename': 'basehttp.py', 'funcName': 'log_message'},  # annoying logging any response to sys.stderr (even if status is 200)
        {'filename': 'options.py', 'funcName': 'construct_change_message'},  # logging `Key not found` if a checkbox was unchecked and isn't present in POST data
    ]
    if any([bool(record.__dict__.viewitems() >= r.viewitems()) for r in logs_to_omit]):
        return False

    return True

我写的测试是：

test_my_logging.py

from django.utils.unittest import TestCase
from my_logging import *
import collections
import mock
from mock import patch
import logging
LOGGER = logging.getLogger(__name__)
log_format = '[%(levelname)s] %(asctime)s %(context)s %(pathname)s:%(lineno)d: %(message)s'
log_time_format = '%Y-%m-%dT%H:%M:%S%z'


class TestMyLogging(TestCase):
    def test_post_log_filter(self):
        self.assertEqual(True, post_log_filter(logging.LogRecord(None, None, None, None, msg=None, args=None, exc_info=None, func=None)))
    
    def test_post_log_filter_false(self):
        record = logging.Formatter([
            {'filename': 'basehttp.py', 'funcName': 'log_message'},  # annoying logging any response to sys.stderr (even if status is 200)
            {'filename': 'options.py', 'funcName': 'construct_change_message'},  # logging `Key not found` if a checkbox was unchecked and isn't present in POST data
        ])
        self.assertEqual(False, post_log_filter(record))

我正在测试两种情况。对于真：不管我为 post_log_filter() 传递什么，我都是真的。所以第一个测试通过了。

我不知道我在通过 record 测试 False 时做错了什么，我也为此得到了 True。所以，测试失败。

你会如何推荐我通过记录以便我得到False。我不允许更改 my_logging.py.

Answer 1

我找到了解决办法。如下修改记录现在测试 False.

def test_post_log_filter_false(self):
    record = logging.makeLogRecord({'filename': 'basehttp.py', 'funcName': 'log_message'})
    self.assertEqual(False, post_log_filter(record))

两个测试都通过了。

如何测试将记录作为参数的函数？

How can I test a function that takes record as a parameter?

python

django

pytest
