This problem was found when I try to package astroid 2.15.6 for ArchLinux. And I noticed that Gentoo deselected this test since 2.15.6 gentoo/gentoo@70a46fc
Thank you for opening the issue. It could be that it's now easier to infer the value of pydantic fields when pydantic is actually installed without any help from the brain. Most libs' brains are tested without the lib being instaled in our continuous integration which could explain the issue. (Need investigation this is all intuition and I'm on mobile).
It seems that pydantic
is missing from the requirements_full.txt.
Note also a similar test where attrs
is required and the test will be skipped if attrs is not installed. attrs is in the requirements_full.txt.
