   [200, {"Content-Type" => "text/html"}, [html]]
  end
end

class TestMyRackApplication < Test::Unit::TestCase
  include Capybara::DSL

  def setup
    Capybara.app = MyRackApplication.new
  end

  def test_title
    visit("/")
    within("h1") do
      assert_equal("Welcome!", text)
    end
  end

  def test_no_sidebar
    visit("/")
    within("body") do
      assert_not_find(".sidebar")
    end
  end

  def test_header_content
    visit("/")
    within(".header") do
      find("ol.navi")
      # This fails with the following message:
      #
      # <"ol.navi">(:css) expected to find an element in
      # <<div class="header">
      #       <p>No navigation.</p>
      #     </div>>
      #
      # This messages shows the current context. You don't need to
      # entire HTML. You just see the current context moved by "within".
      # It helps you debug a problem without save_and_open_page.
    end
  end
