a trivial example

.. sourcecode:: python

import unittest from doublex import Spy, assert_that, called

class SpyUseExample(unittest.TestCase): def test_spy_example(self): # given spy = Spy(SomeCollaboratorClass) cut = YourClassUnderTest(spy)

       # when
       cut.a_method_that_call_the_collaborator()

       # then
       assert_that(spy.some_method, called())
