Save screenshots when using Selenium, Capybara and Ubuntu server

save_screenshots_snippets.rb

#WIP

#spec/spec_helper.rb

RSpec.configure do |config|

  #Only for selenium based tested filtered with :js => true on tests
  #eg:  describe "Some test", :js => true do
  #     end
  config.around(:each, :js => true) do |example|
   Capybara.current_driver = :selenium
   result = example.run
   unless result.blank? || result == true
     require 'selenium-webdriver' #>= 0.2
     #Example failed
     images_root = File.join(Rails.root, 'tmp')
     FileUtils.mkdir_p(images_root) unless File.exists?(images_root)

     file_name = "#{File.basename(example.metadata[:example_group][:file_path]).to_s.underscore.gsub('.','_')}"
     file_name += "_line_#{example.metadata[:example_group][:line_number]}.png"

     page.driver.browser.save_screenshot(File.join(images_root, file_name))
   end

   Capybara.use_default_driver
  end                      

end     

Also - If anyone else gets caught out by the recent issue with shared connections on Active Record (eg. missing data, only when you load on the selenium example) : Add this to your your spec helper (thanks José)

class ActiveRecord::Base
mattr_accessor :shared_connection
@@shared_connection = nil

def self.connection
@@shared_connection || retrieve_connection
end
end

Forces all threads to share the same connection. This works on

Capybara because it starts the web server in a thread.

ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection
