python - pytest - 抑制来自特定 3rd 方模块的 DeprecationWarning

Question

当我运行 pytest 时，我收到了来自 3rd 方库的一些弃用警告。我想知道我自己的代码中的任何弃用警告，但不是在与另一个 3rd 方库捆绑在一起的库的供应商副本中。

This answer帮助我中途到达那里。如果我像这样运行 pytest:$ pytest ./tests/我得到:

但如果我像这样运行 pytest: $ pytest ./tests/ -W ignore::DeprecationWarning我得到:

第二个输出显示过滤器有效，但这也会隐藏我希望看到的由我自己的代码产生的任何弃用警告。

这个问题的一部分是我不确定在忽略过滤器中尝试引用哪个模块。我试过 $ pytest ./tests/ -W ignore::DeprecationWarning:urllib3.*:我试过 $ pytest ./tests/ -W ignore::DeprecationWarning:botocore.*: .这两个结果与第一个没有过滤的示例的输出相同。

如何从 urllib3 的版本中过滤掉 DeprecationWarnings与 requests 的供应商版本一起打包包含在 botocore 中(当我使用 boto3 库运行命令时会调用它)？

Answer 1

您应该使用警告过滤器选项(ini 或标记):

[pytest]
filterwarnings =
    ignore::DeprecationWarning:botocore.*:
