How To Reproduce
Run the tests with python3.11

Your environment
Please run the following and paste the output.

(Gentoo) Linux-5.17.7-gentoo-x86_64-Intel-R-_Core-TM-_i7-10510U_CPU_@_1.80GHz-with-glibc2.35
Python 3.11.0b1 (main, May 11 2022, 10:00:03) [GCC 11.3.0]
pyfakefs 4.6.dev0

Thanks - we haven't yet tried to run tests under 3.11, I will have a look later. These are all pathlib-related tests, and as pyfakefs heavily depends on the real pathlib implementation, it is not unexpected that it breaks with a new Python version.

[mrbean-bremen]

Ok, for my own reference:
In 3.11, the accessor class in pathlib has been removed, which had wrapped all access to os file system functions. Instead, the os functions are called directly now. As we had re-implemented that accessor to access the fake filesystem, this won't work anymore. In principle we could just rely on patching the os functions, this may even be easier, though we have to check how that plays with a faked OS environment, e.g. testing Windows under Linux and vice verse.
I think that most functionality (except for some handling of skip modules) is probably intact, but the tests have to be rewritten to run with a patched enviroment, so that os will be patched in the tests.

Have to look a bit more into this, maybe I will have a closer look over the weekend.

[mrbean-bremen]

Confirming that the only part really broken is the usage of skip modules that call pathlib functions, while the normal patching of pathlib works (just the tests have to be adapted).
I'm not sure yet how to fix the skip module problem, so this may take a bit.

@AndrewAmmerlaan - it should be fixed in master now. I would appreciate if you could test this version - there may be more problems (or regressions from the fix) under Python 3.11 that don't show up in the tests.

Great, thanks for looking into it. We currently have two direct dependencies of pyfakefs with python3.11 in Gentoo, I ran both their tests and the pyfakefs tests and found no failures. I'll let you know if I find any additional problems later.

Thanks - good to have some real life tests before making a release!
