rspec users - Nov 2008 - Spec rendering xml.erb suspectly doen''t work

I have to spec an contoller action witch is (only) rendering an
xml.erb template.
The action looks like this:

  def index
    respond_to do |format|
      format.xml
    end
  end

The "index.xml.erb" template includes (for now) only the string
"XML".

This works fine if I requests the action with curl -H "ACCEPT:
text/xml" ...
It also running fine, if I write a conventional rails functional test.

But specing this, it render nothing but a single blank.

  describe PostsController do
    it "should render xml" do
      request.env["HTTP_ACCEPT"] = "application/xml"
      get :index
      response.body.should == "XML"
    end
  end

  $ spec spec
  1)
  ''PostsController should render xml'' FAILED
  expected: "XML",
       got: " " (using ==)
  /home/petehr/Project/test/spec/controllers/posts_controller_spec.rb:7:

I''ve done some puts-debugging like this

  format.xml { puts ">>>#{render_to_string}<<<" }

in the actions respond_to block. Running the curl command or the functional
test shows the expected result ">>>XML<<<". But
runing the spec again
shows only a blank: ''>>> <<<''.

Any hints?

By default, controller specs don''t actually render the views.  You need
to call integrate_views from within your example group to make them
render.

Ah. Ok thanks.
