Best way to debug rspec integration tests with capybara?

Question

I have an rspec test failing, but in development, when I perform the actions myself, the page renders correctly.

Here's the snippet:

describe "sign up process" do

let (:admin1) { FactoryGirl.create(:admin) }

describe "with valid information"

  before do 
    visit new_admin_registration_path
    fill_in "Email", with: admin1.email
    fill_in "Password", with: admin1.password
    fill_in "Password confirmation", with: admin1.password_confirmation
    click_button "Sign up"
  end

  it { should have_selector('div.alert') }
end

It's not finding that selector at all, but I confirmed it exists when viewing the source using the development environment.

What I'd like to be able to do is inspect the page that's rendering to see what I'm missing. Is there a way to do that?

Capybara has a method save_and_open_page which will open a new browser window with the current state of the page (it requires the launchy gem).

For example:

  before do 
    ...
    click_button "Sign up"
    save_and_open_page
  end
