A fix has been pushed upstream on the main branch of beartype: https://github.com/beartype/beartype/commit/ee167cf294cf65c4725b0242556c08e9ccd784bb

It's likely to be part of the next release of beartype.

Exact line is: https://github.com/kdeldycke/meta-package-manager/actions/runs/23897036306/job/69684170316#step:3:3965

test_door_is_bearable_warnings fails when the test suite runs more than once in the same environment (e.g., when aur-install retries a failed dependency layer). The first run passes, the second fails with:

E  Failed: DID NOT WARN. No warnings of type
E  (<class 'beartype.roar.BeartypeDecorHintPep585DeprecationWarning'>,) were emitted.
E  Emitted warnings: [].

This is a memoization issue in beartype: reduce_hint_pep484_deprecated() caches its result on the first call, so the warning is only emitted once. On subsequent runs within the same environment, the cached path skips the warning entirely.

beartype's own CI passes because the suite only runs once per job. The test's own comments acknowledge the fragility ("unintended ordering issues with other tests due to memoization").

Filed upstream: https://github.com/beartype/beartype/issues/631

A workaround for the PKGBUILD would be to exclude the flaky test in check():

pytest -k "not test_door_is_bearable_warnings"

Reproduced on Python 3.14.3, beartype 0.22.9, Arch Linux rolling (greyltc/archlinux-aur:yay). CI logs: https://github.com/kdeldycke/meta-package-manager/actions/runs/23897036306/job/69684170316

I get same errors as carlosal1015 in a clean chroot env.

@carlosal1015 Should be fixed in 0.18.5-3.

Need co-maintainer for faster development response.
