Hello all,

Does anyone know a good way to test function objects? It's easy enough 
to test class attributes, but for some reason I'm finding it difficult 
to test if a function has the right 'attributes'.

I'm using unittest and nosetests.

Sample function:

def foo():
     x = 3
     y = 4

This example is super simple but lets pretend that x and y were derived 
from some more complicated code that was done inside the function. The 
best way I can come up with is moving the complicated code into another 
function that returns the derived value and then test the return value, 
but if i want to keep the code in the function how can I get to those 
'attribute' values to test?
