rspec users - Nov 2011 - Problem with mocking helper methods

Given that I assume that rails helper image_tag works as intended, I
want  to mock out call to this method in my helper.

spec/helpers/some_helper_spec.rb:
require ''spec_helper''
describe SomeHelper do
   it  ''allows stub tags'' do
        helper.should_receive(:image_tag).with(2).and_return(3)
        helper.image_tag(2).should == 3
   end
end

result:
        Failure/Error : helper.image_tag(2).should == 3
        expected : 3
        got : "<img alt=\"2\" src=\"/assets/2\"
/>" (using ==)

Bundle:
  * rspec (2.7.0)
  * rspec-core (2.7.1)
  * rspec-expectations (2.7.0)
  * rspec-mocks (2.7.0)
  * rspec-rails (2.7.0)
  * rails (3.1.1)

Unfortunately, I copied the example (from ''it'' to
''end'') directly into a helper spec and it passed :(

Are there any other testing related gems in your Gemfile that might be gumming
things up?
