一、在pytest.ini配置如下配置
cli live log 部分配置是实时日志，即自动化脚本执行的过程中实时输出，方便调试脚本使用，capture log则是当脚本失败了，会在执行日志的最后将失败的用例中的日志打印输出，便于定位失败的脚本，尤其在执行大量的脚本时，实时日志很难找到报错的位置，capture log则把失败的日志在最后重新打印一遍，如此则非常方便问题定位
[pytest]
# cli live log
log_cli = True
log_cli_level = info
log_cli_format = %(asctime)s %(levelname)s %(message)s
log_cli_date_format = %Y-%m-%d %H:%M:%S
# capture log
log_format = %(asctime)s %(levelname)s %(message)s
log_date_format = %Y-%m-%d %H:%M:%S
log_level = info二、脚本中使用方法
直接导入logging，然后直接调用logging的info，error，warnning等方法写日志即可，如下演示一个成功的测试函数，一个失败的测试函数，capture log只会捕获失败的用例的日志
import logging
def test_func1():
logging.info("info log in test_func1...")
logging.error("error log in test_func1...")
logging.warning("warnning log in test_func1...")
def test_func2():
logging.info("info log in test_func2...")
logging.error("error log in test_func2...")
logging.warning("warnning log in test_func2...")
assert 1==2执行结果如下：
