Unable to find xpath "/html - Capybara

Question

I created tests for my rails application using Capybara. I have one failing test without any idea how to fix.

Failures:

1) ManageController ManageController check user login to manage admin success
     Failure/Error: page.should have_content("Login")
     Capybara::ElementNotFound:
       ****Unable to find xpath "/html"****

Code:

describe "POST perform_login" do
  it ("check user login to manage admin success") do
    visit('/manage')
    page.should have_content("Login")
    fill_in('email' , {:with=> 'moshe.tini@conduit.com'})
    fill_in('password', {:with=>'1234'})
    button_link 'submit_login'
    page.should have_content("Fake Login")
  end
end

Can you post your code in for "login"?

Here's an example... I went to google and searched "San francisco" and inspected the first link.

The link has a structure like this:

<h3 class="r">
  <a href="/link">

In this case, I'd just do:

page.should have_selector('.r a')

If you're looking for a certain text within the url, you could then do:

url_text = page.find('.r a').text
url_text.should include("foo")
