[TIP] Struggling with pymock

I am struggling with the basics of pymock. Here is a simplified example
class I'd like to test:
def __init__(self, cf):
self.conffile = cf
f = open(self.conffile)
# read and assign
What I'd like to test is whether the constructor correctly opens a file
and reads and assigns its contents to some member variables.
What I'd do with conventional unit testing would be to create a fake
conffile with some data, have it read by __init__ and then compare what
has been read with what I set up.
Now what I imagined to do with pymock was to stub out
__builtins__.open(). But I could't get pymock to handle the
self.conffile argument to open() correctly.
I feel like I am looking at the whole pymock testing from the wrong way,
since I can't get such a simple example to work. Can someone enlighten me?
