Mocks suck.

#RSpec Mocks...
it "does something with a collaborator" do
        #Given
	collab = mock(:collab)
	it.collaborator = collab
     
        #Then
        collab.should_receive(:call).with(3)

        #When
	it.do_something
end

#Spies using RR...
it "does something with a collaborator" do
        #Given
	collab = Object.new
        stub(collab).call
	it.collaborator = collab

        #When
	it.do_something

        #Then
	collab.should have_received.call(3)
end

02_irrelevant_collaborations.rb

#object code:
def my_awesome_method
  logger.debug("Doing stuff with #{@collaborator.inspect}")
  @collaborator.do_stuff
end

#RSpec Mocks:
it "should do stuff with collaborator" do
  collaborator = mock(:collaborator_is_a_weird_looking_word)
  collaborator.stub!(:inspect)

  collaborator.should_receive(:do_stuff)

  object.collaborator = collaborator

  object.my_awesome_method
end

#Spies using RR
it "should do stuff with collaborator" do
  collaborator = Object.new
  stub(collaborator).do_stuff
  object.collaborator = collaborator

  object.my_awesome_method

  collaborator.should have_received.do_stuff
end

#And then... what happens to the tests when we remove the debugging code?
def my_awesome_method
  @collaborator.do_stuff
end

Seriously guys, just go get RR and then do this:

Spec::Runner.configure do |config|
  config.mock_with :rr
  # or if that doesn't work due to a version incompatibility
  # config.mock_with RR::Adapters::Rspec
end
