python - 为什么 python 日志记录日志文件不按顺序？

标签 python testing logging automation

我有方法:

def custom_logger():
    logger_name = inspect.stack()[1][3]
    logger = logging.getLogger(logger_name)
    logger.setLevel(logging.DEBUG)
    console_handler = logging.StreamHandler()
    file_handler = logging.FileHandler(os.path.join(os.path.pardir, os.path.pardir, os.path.pardir, "resources", "automation.log"), mode='w')
    file_handler.setLevel(logging.DEBUG)
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(funcName)s - %(levelname)s: %(message)s',
                                  datefmt='%m/%d/%Y %I:%M:%S %p')
    file_handler.setFormatter(formatter)
    console_handler.setLevel(logging.WARNING)
    console_handler.setFormatter(formatter)
    logger.addHandler(file_handler)
    logger.addHandler(console_handler)
    return logger

我在我的自动化测试框架中使用它。我在页面的方法中调用了方法。但是在运行测试后，我发现日志文件不正确。

如您所见，它们以某种奇怪的顺序分组。

有谁知道日志组是如何记录日志的？因为目前如果你从一个测试中检查我的日志的时间顺序，应该一一显示哪些方法，你会发现它们没有顺序。

最佳答案

原因是它重复了处理程序。

解决方案是添加检查处理程序是否存在:

def custom_logger():
    logger_name = inspect.stack()[4].function
    logger = logging.getLogger(logger_name)
    logger.setLevel(logging.DEBUG)

    if not logger.handlers:         # THIS LINE WAS ADDED.
        console_handler = logging.StreamHandler()
        console_handler.setLevel(logging.WARNING)
        formatter = logging.Formatter('%(asctime)s - %(name)s - %(funcName)s - %(levelname)s: %(message)s',
                                      datefmt='%m/%d/%Y %I:%M:%S %p')
        console_handler.setFormatter(formatter)
        logger.addHandler(console_handler)

        file_handler = logging.FileHandler(os.path.join(os.path.pardir, os.path.pardir, os.path.pardir, "resources", "automation.log"), mode='a')
        file_handler.setLevel(logging.DEBUG)
        file_handler.setFormatter(formatter)
        logger.addHandler(file_handler)

    return logger
