System fixtures

A collection of Python fixtures to fake out various system resources (processes, users, groups, etc.).

Each fake resource typically behaves as an "overlay" on the real resource, in that it can be programmed with fake behavior for a set of inputs, but falls back to the real behavior for the rest.

>>> import pwd

>>> from systemfixtures import FakeUsers

>>> users = FakeUsers()
>>> users.setUp()

>>> pwd.getpwnam("foo")
Traceback (most recent call last):
...
KeyError: 'getpwnam(): name not found: foo'

>>> users.add("foo", 123)
>>> info = pwd.getpwnam("foo")
>>> info.pw_uid
123
>>> users.cleanUp()
