Pytes正确的配置使用日志功能

Pytes正确的配置使用日志功能

在pytest自动化测试中,如果只是简单的从应用的角度来说,完全可以不去了解pytest中的显示信息的部分以及原理,完全可以通过使用推荐的pytest.ini配置,从而可以做到相对来说比较通用的日志配置。
这里我们推荐使用如下配置,其中log_cli 相关的四条配置是用来配置live log即实时日志的,而其他三条配置则是用例配置capture log即捕获日志的。分别对他们的日志级别、日志格式、时间戳格式进行了设置,比如这里日志级别都设置为info,当然如果脚本稳定之后,提交自动化测试代码仓库时可以将日志级别调整为warning。

[pytest]
log_cli = True
log_cli_level = info
log_cli_format = %(asctime)s | %(levelname)s | %(filename)s:%(lineno)s | %(message)s"
log_cli_date_format = %Y-%m-%d %H:%M:%S

log_level = info
log_format = %(asctime)s | %(levelname)s | %(filename)s:%(lineno)s | %(message)s"
log_date_format = %Y-%m-%d %H:%M:%S

下面用一个简单的测试脚本来展示一下上述日志配置的效果。

import logging

def test_demo():
    logging.debug("this is debug log ...")
    logging.info("this is info log ...")
    logging.warning("this is warning log ...")
    logging.error("this is error log ...")
    logging.critical("this is critical log ...")
    assert 1==2

执行结果如下,可以看出这里显示了实时日志(live log),同时未显示debug级别的日志,捕获日志(capture log)同样也未显示debug级别的日志,而且时间戳和日志格式相对来说都是比较符合实际应用的,因此这里的推荐的pytest.ini中对日志的配置,完全可以拿去直接使用。
