How to mock os.walk in python with a temporary filesystem using monkeypatching(PyTest)?

I have a function that uses os.walk and I want to test it using monkeypatching (PyTest). I don't know how to use monkeypatch.setattr.

To achieve correct mock of the os.walk, you have to use 

monkeypatch.setattr(os, "walk", function_that_will_simulate_os_walk_iterator)

The function_that_will_simulate_os_walk_iterator should return a list of tuples (root, dirs, files) for each simulated file.
