【pytest-10】report报告+失败重跑

前言

做web自动化的小伙伴应该都希望在html报告中展示失败后的截图，提升报告的档次，pytest-html也可以生成带截图的报告

conftest.py

1、失败截图可以写到ocnftest.py文件里，这样运行用例时，只要检测到用例实例，就调用截图的方法，并把截图保存到html报告上

#调用谷歌驱动

切换到项目所在的根目录运行：

pytest --html=report.html --self-contained-html

 生成报告如下：

 失败重试

失败重跑需要依赖pytest-rerunfailures插件，使用pip安装就行

pip install pytest-rerunfailures

  用例失败再重跑1次,命令行加个参数--reruns就行了

 关于reruns参数的2个用法

re-run failing tests to eliminate flaky failures：

--reruns=重新运行失败测试的次数。默认为0。
--reruns delay=重播延迟
添加重新运行之间的时间（秒）延迟。
