I can't get minimock and nosetests to play nice

[Matthew Wilson]

I'm curious if anyone has ever tried using nosetests along with
minimock.

I'm trying to get the two to play nice and not making progress. I
also wonder if I'm using minimock incorrectly.

Here's the code I want to test, saved in a file dtfun.py.

class Chicken(object):
"I am a chicken."
def x(self): return 1
def z(self): return 1

def g():

"""
Verify that we call method x on an instance of the Chicken class.

# First set up the mockery.

>>from minimock import Mock
Chicken = Mock('Chicken')
Chicken.mock_returns = Mock('instance_of_chicken')

Now this stuff is the real test.

>>g()

Called Chicken()
Called instance_of_chicken.x()
"""

# This is what the function does.
c = Chicken()
c.x()

if __name__ == "__main__":

# First set up the mockery.
from minimock import Mock
Chicken = Mock('Chicken')
Chicken.mock_returns = Mock('instance_of_chicken')

# Now run the tests.
import doctest
doctest.testmod()

Here's the results when I run the code using doctest.testmod (which
passes) and nosetests --with-doctest (KABOOM):

$ python dtfun.py # Nothing is a good thing here.

$ nosetests --with-doctest dtfun.py
F

It seems like nose isn't building the mock objects.

Any ideas?

This has nothing to do with nose.

class Chicken(object):

>>from minimock import Mock
>>Chicken = Mock('Chicken')
>>Chicken.mock_returns = Mock('instance_of_chicken')

This does not rebind the module global name "Chicken".

Now this stuff is the real test.

>>g()

Called Chicken()
Called instance_of_chicken.x()

g() returns None, and prints nothing.

.... because g() returns None, and prints nothing.

Any ideas?

Read the Python tutorial, write some Python code and some doctests
without using minimock. Google about Python scoping rules. Read the
doctest docs about the global namespace seen by doctest-ed code:
