Hello all,

My first question, in my controllers, do I need to test respond_to is
returning the correct data for its mime-type?

In my controller spec I have

it "creates a list of available types for that category" do
      xhr :get, :index_available, :category_id => 1, :format => :json
      assigns[:types].should have(1).record
end

and in my logs I see (406 Not acceptable....)

Processing TypesController#index_available to json (for 0.0.0.0 at
2011-05-02 13:20:01) [GET]
  Parameters: {"category_id"=>"1"}
Completed in 1ms (View: 0, DB: 0) | *406* Not Acceptable [
http://test.host/categories/1/types/index_available.json]
  SQL (0.1ms)   ROLLBACK
  SQL (0.0ms)   BEGIN

But I get a green pass.

If I change :format => :json to 'json', I get a load of errors (which I have
mentioned before on this list but haven't had time to address the situation)

So, two pronged question, do I need to test :json (seeing as I'm not testing
the contents) and can anyone shed any light on my 406 and/or the errors when
changing the format to 'json'

Many thanks
