Getting mock objects from different libraries

"""Mocker:

Mocks are obtained from a mocker instance, which is created 
automatically if you create a test case that inherits from 
MockerTestCase.
"""
from mocker import Mocker, MockerTestCase

class TestCaseForMocker(MockerTestCase):

    def test_something(self):
        a_mock = self.mocker.mock()

    mocker = Mocker()

"""Flexmock:

Mocks are obtained by calling flexmock(), which can take a 
variety of arguments to further detail their behaviour."""

from flexmock import flexmock

def flexmock_test():
    a_mock = flexmock()

"""Fudge:

There are two ways mocks are obtained in Fudge. The neater 
way, which  I'll call the "implicit" way, is with the 
fudge.patch decorator, which performs both creation of the mock,
and substituting it into the namespace of the test."""

"""Mock:

mock.Mock() gives you a mock.
