rspec users - Aug 2007 - Specifying custom rails FormBuilders

I want to write a spec for a custom form builder, but I''m not really 
sure where it should live or how to include the right rspec_on_rails 
contexts.  Ideally, I should be able to write a spec like:


describe LabelledBuilder do
 
  it "should let me create a text field" do
    object = mock(object)
    object.stub!(:attribute).and_return("Test String")
   
    render :inline =>
      "<% form_for(@object, :builder => LabelledBuilder) do |f|
-%>
        <%= f.text_field :attribute %>
       <% end %>"
       
    response.should have_tag("label")
  end
end


but I''m not having much luck.  Can anyone give me an idea where to
start?

How so? What error do you get from that?

Well, if I put it in spec/helpers, where I expected it to work, I get:

NoMethodError in ''LabelledBuilder should let me create a text
field''
undefined method `render'' for [Dynamically generated class for RSpec 
example]:#<Class:0x35e4d38>
./spec/helpers/labelled_builder_spec.rb:15:

If I instead put it in spec/views, I get:

Exception in ''LabelledBuilder should let me create a text
field''
Unhandled render type in view spec.
/Users/jay/Documents/eclipse/mediajoint/vendor/plugins/rspec_on_rails/lib/spec/rails/dsl/behaviour/view.rb:133:in
`subject_of_render''

`render''
./spec/views/labelled_builder_spec.rb:15:

which makes sense, since subject_of_render doesn''t seem to handle
inline
rendering...  but of course, if I move it out into a file and render it 
there, I have to make one fake view per test case.
