class Object
# Create a mock method on an object. A mock object will place an expectation
# on behavior and cause a test failure if it's not fulfilled.
#
# ==== Examples
#
# my_string = "a wooden rabbit"
# my_string.mock!(:retreat!, :return => "run away! run away!")
# my_string.mock!(:question, :return => "what is the airspeed velocity of an unladen sparrow?")
#
# # test/your_test.rb
# my_string.retreat! # => "run away! run away!"
# # If we let the test case end at this point, it fails with:
# # Unmet expectation: #<Sparrow:1ee7> expected question
#
