rspec users - Oct 2008 - Stubbing #javascript_include_tag in a helper spec

When writing specs for a helper method, how do you set an expectation  
for #javascript_include_tag ?

describe NeighbourhoodsHelper do
   describe ''#initialise_map'' do
     it ''should include the "foo" JS file'' do
       # expectation here
       helper.foobar
     end
   end
end

I''ve tried replacing "# expectation here" with the following,
but none
of them result in the desired behaviour:

ActionView 
::Helpers::AssetTagHelper.should_receive :javascript_include_tag
@controller.should_receive :javascript_include_tag
@controller.instance_eval  
{ @template }.should_receive :javascript_include_tag

Thanks!

Assuming that you intend to have a helper method that calls out to
javascript_include_tag, then:

  helper.should_receive :javascript_include_tag

Let us know if that works for you.
