你们搜索这个文件内容，关于allure的内容，都是我们做了修改的~
2、conftest.py配置
删除原本安装的pytest_playwright插件：
在settiings中找到pytest_playwright,点击减号就可以删除了~
3、修改pytest.ini文件
--tracing=retain-on-failure--screenshot=only-on-failure--video=retain-on-failure
4、运行case
此时运行case，当case失败时，我们可以看到这个目录：
里面就是截图，录屏，以及路由追踪~
5、注意事项
如果conftest.py中配置了如下内容：
要保证json文件中有值，否则会报错~
