Rails 3 integration test fails with 406 response for simple html request_问答_开发者

I have an integration test the sends a simple GET request to the 'show' action. I get a when I assert_response :success, it fails because the response is a 406, which means the format is Not Acceptable HTTP.

require 'test_helper'

class UserFlowsTest < ActionDispatch::IntegrationTest
  fixtures :continents, :countries, :types

  test "browse register order" do
    docs = make_docs
    assert_equal Doc.count, docs.length, "Docs not created properly"
    bob=new_session_as(:bob)
    bob.goes_to_home
    bob.goes_to_doc(1)
  end

  private

  module TestDSL
    def goes_to_home
      get root_url
      test_results("docs/index")
    end

    def goes_to_doc(id)
      get docs_url(id), #{:format => :html} - fails with this as well...
      y request.inspect
      p response.inspect
      test_results("docs/show")
    end

    def test_results(path)
      assert_response :success, "Checking #{path}"
      assert_template path
    end
  end #module TestDSL



  def new_session_as(person)
    new_session do |sess|
      #sess.goes_to_login
      #sess.logs_in_as(person)
      yield sess if block_given?
    end
  end

  def new_session
    open_session do |sess|
      sess.extend(TestDSL)
      yield sess if block_given?
    end
  end

end

Here is the request.inspect output:

the 'goes_to_home' test works as expected. Using the page in the development environment on my pc also works fine. Here is the server console output:
