I'm getting AttributeError: 'NoneType' object has no attribute 'rsplit' error when trying to run this code self.client.get("/"). Test running in Docker on Windows 10 machine. Other simple model tests are running good, just like the application itself. Also tried running this test in another project, and there wasn't any problems. Feel free to ask for more information if needed.
The whole error:

Looking at the traceback, it seems that settings.DEFAULT_FILE_STORAGE is None.
It seems you're getting it from a dotenv. Are you sure it is defined inside and your dotenv is found ?
