pytest学习08--html报告报错截图+失败重跑

前言：

　　做web自动化的小伙伴应该都希望在html报告中显示失败后的截图，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conftest.py文件里，这样用例运行时，只要检测用到用例实例，就调用截图的方法，并且把截图保存到html报告上

    browser.get("https://www.cnblogs.com/yoyoketang/")
    time.sleep(3)
    t = browser.title
    assert t == "上海-悠悠"
    browser.close()

　　报告展示内容：

在CMD终端执行：pytest -s test_o1.py --html=report.html --self-contained-html

生成的报告如下：

 

 

 

失败重试：

用例失败再重测1次，命令行加个参数--rerun就可以了

pytest --reruns 2 -s test_o1.py --html=report.html --self-contained-html
