Question

我有一个 myfun.py文件与我的功能。
我有一个 test_myfun.py文件与 pytest测试。

运行时pytest test_myfun.py ，测试本身运行没有错误，但 pytest 给出警告。

Answer 1

你有两个选择。

1) 升级您的软件包，即最新版本的 html5lib和 scrapy已修复这些警告。

2) 创建一个 pytest.ini文件在你的 repo 的根目录中，并给它这些内容，这将使 pytest忽略 DeprecationWarning

[pytest]
filterwarnings =
    ignore::DeprecationWarning
