Python 3.3 introduced os.supportsdirfd to check if some os functions do accept a file descriptor instead of a path. The problem is that os.supportsdirfd is a list of functions, not a list of function names. If os functions are monkey patched, you cannot test anymore if a function supports file descriptor.
If you're monkey-patching the function, you can monkey-patch os.supports_dir_fd too.
Monkey patching is a common practice in Python. testos.py replaces os.exec*() functions temporary for example.
For testing, yes. It's not recommended for production code.
