How to test code that uses weakrefs

We've got a library that supports py 3.8 .. 3.12
I though I'd give it a go with newest pypy release, and a couple of unit
tests fail.
I've traced it down to the expectation that objects will disappear from
weakref.WeakKeyDictionary.

In some cases, this is a user-facing thing, we issue a warning for "unused"
resources, by virtue of them missing from the weak container when we expect
the user code to keep the reference around.

Is there a good idiom or some way to support this behaviour with pypy?

Thanks,
Dima Tisnek
