assert_select / assert_tag issue

Upgraded to RoR 2.0 on Mac OS X -
and cannot seem to get assert_select or the supposedly deprecated
assert_tag to work. - Asserts are fairly simple and so is the page being
tested - see below for HTML and different errors.

Any help is greatly appreciated!

thanks
Jim.

class UserControllerTest < Test::Unit::TestCase
  def setup
    @controller = UserController.new
    @request = ActionController::TestRequest.new
    @response = ActionController::TestResponse.new
  end

  # Make sure the registration page responds with the proper form.
  # Make sure the registration page responds with the proper form.
  def test_registration_page
    get :register
    title = assigns(:title)
    assert_equal "Register", title

    assert_response :success
    assert_template "register"
    # NONE OF THESE WORK....
    assert_select "title", "Register"
    assert_select "form"
    assert_select "form[action=/user/register]"
    assert_tag "form", :attributes => { :action => "/user/register",
                                        :method => "post" }

  end
end

None of the 4 assert_* at the end work...
These are the errors I get as I rotate the asserts...
