Why FileNotFoundError on Path.rename while using Pyfakefs?

importlib_resources backport not compatible with pyfakefs?

QUESTION

Why FileNotFoundError on Path.rename while using Pyfakefs?

Asked 2022-Apr-02 at 14:13

I wrote a test for a function that renames files from e.g. /videos/vid_youtube.mp4 to /videos/youtube/vid.mp4. The test patches the fs with Pyfakefs.

When the code actually renames the file, I get this error.

The problem here is most likely the static initialization of Dirs.VIDEOS. This is initialized at load time as a pathlib.Path, and won't be patched later at the time you setup pyfakefs (the same problem would happen if you where to use unittest.patch for patching).

There are two ways to fix this:

adapt the code to not initialize the path statically
This could be done by statically defining the str path, and converting it to a Path at run time, or by using a method to get the path instead of an attribute (e.g. Dirs.VIDEO() instead of Dirs.VIDEO`).
adapt the test to reload the tested code
If reloading the tested code after pyfakefs has been initialized, it will be correctly patched. pyfakefs provides an argument in setUpPyfakefs that does that:

QUESTION

importlib_resources backport not compatible with pyfakefs?

Asked 2020-Feb-05 at 19:28

I'm refactoring a library to use importlib.resources for python 3.7+. I'm using the importlib_resources backport for python 3.6 compatibility. The code works for pythons 3.6-3.8. However, the pytest tests, using pyfakefs, fail for 3.6. Under testing conditions, the path returned from use of importlib_resources is mangled (but under "real-world" conditions they return correctly).

A minimal example: I have the following library structure:

The fake filesystem in pyfakefs is empty at test start (except for the temp file path needed by the tempfile module), so if you want to access any files in the real filesystem in your test, you have to map them into the fake filesystem:
