Question

我正在创建一个自定义日志记录模块，以便在应用程序框架中实现。我正在使用PyCharm，unittest模块和nosetests作为我的测试运行员。

这是一个简单的测试用例，但它没有像我希望的那样将输出保存到文件/tmp/test.log。

import unittest
import logging

class Logger_class____test_cases(unittest.TestCase):
    def test_log_file_basics(self):
        # set up logging to file - see previous section for more details
        logging.basicConfig(level=logging.DEBUG,
                            filename='/tmp/test.log')
        # define a Handler which writes INFO messages or higher to the sys.stderr
        console = logging.StreamHandler()
        console.setLevel(logging.INFO)
        # set a format which is simpler for console use
        formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s')
        # tell the handler to use this format
        console.setFormatter(formatter)
        # add the handler to the root logger
        logging.getLogger('').addHandler(console)

        # Now, we can log to the root logger, or any other logger. First the root...
        logging.info('Jackdaws love my big sphinx of quartz.')

        # Now, define a couple of other loggers which might represent areas in your
        # application:
        logger1 = logging.getLogger('myapp.area1')
        logger2 = logging.getLogger('myapp.area2')

        logger1.debug('Quick zephyrs blow, vexing daft Jim.')
        logger1.info('How quickly daft jumping zebras vex.')
        logger2.warning('Jail zesty vixen who grabbed pay from quack.')
        logger2.error('The five boxing wizards jump quickly.')

如何通过nosetests将日志输出写入文件？它似乎与捕获stdout和stderr的测试有关，但我似乎无法弄明白。

我从Python logging cookbook获得了代码。

我明白了。我在框架中的全局模块中配置了默认日志文件名。

我有类似以下的内容覆盖了我的测试用例：

logging.basicConfig(level=logging.DEBUG,
                        format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
                        datefmt='%m-%d %H:%M',
                        filename='log_file_name.log',
                        filemode='w')

当然墨菲定律，如果我发一个问题，我会很快找到答案。洛尔
