retrieve_user, the real method, sets an instance variable that other
methods expect to be set rather than returning a value. When this is
stubbed with a *return value* of the user, the instance variable never
gets set inside the controller.

I'd add a current_user method that returns @current_user, and then
stub *that* in the code examples:

# in ApplicationController

def current_user
  @current_user
end

# in MotionsController

def show
  ...
  if is_showable?(current_user, @motion)
  ...
end

# in example

controller.stub!(:current_user).and_return(@current_user)

HTH,
