rspec users - Mar 2011 - Counter.should_not_receive(:message) not working?

I''m trying to test a Rails controller and am having trouble getting
SHOULD_NOT_RECEIVE to work on a class method. I can never get
Counter.should_not_receive(:xxx) to fail when the message
''xxx'' is sent.

Controller:
def show
  @counter = Counter.increment if count_me
end


RSpec:
describe ''Show'' do
  it "should INCREMENT only when count-me is true" do
    Counter.should_receive(:increment)
    Counter.should_receive(:increment).never
    Counter.should_not_receive(:increment)
    get :show, :count_me => ''true''
  end
end

Why does this pass? Counter.should_receive(:increment) passes
correctly (or fails if COUNT_ME isn''t set correctly), but
shouldn''t the
next 2 statements fail?

This is in Rails 2.3.11 & MongoDB.

Thanks!

Even simpler...

describe ''Show'' do
  it ''should fail because increment is called'' do
    Counter.should_not_receive(:increment)    # Incorrectly passes
    get :show, :count_me => ''true''
  end
  it ''should fail because increment is not called'' do
    Counter.should_receive(:increment)    # Correctly fails
    get :show
  end
end

Should this be params[:count_me]? ---^

Best,

I would say "count_me" is not returning what you think it is. Try
adding
"raise count_me.inspect" in the controller action to see if this is
the
case.

Thanks for the feedback. The code snippet isn''t the exact code, it is 
simplified to demonstrate the problem I''m having (or think that
I''m
having). I know that the count_me values are set correctly when 
experiencing this problem. I also know when the Counter methods are 
executed or not (lots of ''puts''!), so I''m sure that
the Counter is
receiving the message but the .should_not_receive isn''t raising an 
error.

I''m probably doing something incorrect w/r/t the way you''re
supposed to
use mocks in RSpec, but so far I haven''t found what that is.

Please post a single, complete example in a gist that we can copy into a file
and run so we can see the problem locally.
