[FantasqueX]

Steps to reproduce

1. git clone https://github.com/pylint-dev/astroid.git
2. python3.12 -m virtualenv .venv
3. source ./.venv/bin/activate.fish
4. pip install -e .
5. pip install pydantic
6. pytest

Current behavior

Expected behavior

Test passes.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

3.2.0-dev0

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.
