Use Cucumber and Culerity to run Celerity (a headless browser with JS support)

common_celerity.rb

require 'culerity'

Before do
  $server ||= Culerity::run_server
  $browser = Culerity::RemoteBrowserProxy.new $server, {:browser => :firefox}
  @host = 'http://www.google.com'
end

at_exit do
  $browser.exit
  $server.close
end

When /I press "(.*)"/ do |button|
  $browser.button(:text, button).click
  assert_successful_response
end

When /I follow "(.*)"/ do |link|
  $browser.link(:text, /#{link}/).click
  assert_successful_response
end

When /I fill in "(.*)" for "(.*)"/ do |value, field|
  $browser.text_field(:id, find_label(field).for).set(value)
end

When /I fill in "(.*)" for the field named "(.*)"/ do |value, field|
  $browser.text_field(:name, field).set(value)
end


When /I check "(.*)"/ do |field|
  $browser.check_box(:id, find_label(field).for).set(true)
end

When /^I uncheck "(.*)"$/ do |field|
  $browser.check_box(:id, find_label(field).for).set(false)

  $browser.select_list(:id, find_label(field).for).select value
end

When /I choose "(.*)"/ do |field|
  $browser.radio(:id, find_label(field).for).set(true)
end

When /I go to (.+)/ do |path|
  $browser.goto @host + path_to(path)
  assert_successful_response
end

When /I wait for the AJAX call to finish/ do
  $browser.wait
end

Then /I should see "(.*)"/ do |text|
  # if we simply check for the browser.html content we don't find content that has been added dynamically, e.g. after an ajax call
  div = $browser.div(:text, /#{text}/)
  begin
    div.html
  rescue
    #puts $browser.html
    raise("div with '#{text}' not found")

end

Then /I should not see "(.*)"/ do |text|

  div.should be_nil

    raise "Brower returned Response Code #{$browser.page.web_response.status_code}"

end

Google.feature

Feature: Google
    In order to test a remote site
    I surf to google
    And take a look

    Scenario: Trying Google
        When I go to the homepage
		And I fill in "Aslak Hellesoy" for the field named "q"
		And I press "Google Search"
		Then I should see "So little to do - so much time"

paths.rb

# complete rip-off what is generated in a new rails project: features/support/paths.rb

  # Add more mappings here.

  else
    raise "Can't find mapping from \"#{page_name}\" to a path.\n" +
