ruby on rails - Why do RSpec feature specs using Capybara, Poltergeist and Javascript fail inconsistently? -

hi fellow software developers,

i have rails app usual testsuite set (rspec, capybara, poltergeist, jquery, rails). use little javascript(jquery) remote requests. works , don't understand problem yet. may update question further knowledge.

maybe give me hints investigate before post lots of irrelevant code , config.

the inconsistent , unexpected behaviour in feature spec tests via poltergeist in capybara user interaction (clicking forms , links) hides , shows html-elements via ajax jquery.

it seemed works correctly if test manually. setting capybara default time wait changed time had wait until spec run =). found no other relevant configuration or usage yet.

so help/idea appreciated. in advance.

my spec_helper:

require 'simplecov' require 'rubygems'  env["rails_env"] ||= 'test' require file.expand_path("../../config/environment", __file__) require 'email_spec' require 'rspec/autorun' require 'rspec/rails' require 'capybara/rspec' require 'capybara/poltergeist' require 'capybara/rails'  capybara.javascript_driver = :poltergeist  dir[rails.root.join("spec/support/**/*.rb")].each {|f| require f}  rspec.configure |config|   config.include(emailspec::helpers)   config.include(emailspec::matchers)   config.include capybara::dsl   #config.include capybara::rspecmatchers   config.mock_with :rspec    config.fixture_path = "#{::rails.root}/spec/fixtures"    # if you're not using activerecord, or you'd prefer not run each of   # examples within transaction, remove following line or assign false   # instead of true.   # set false capybara + database cleaner   # set true activerecord::base patch jose valim , without database cleaner   config.use_transactional_fixtures = false   config.infer_base_class_for_anonymous_controllers = true   config.order = "random"   config.include factorygirl::syntax::methods    config.after(:each)     # model deletion     model.delete_all   end    config.include featurehelpers end  class activerecord::base   mattr_accessor :shared_connection   @@shared_connection = nil    def self.connection     @shared_connection || retrieve_connection   end end  # # forces threads share same connection. works on capybara # # because starts web server in thread activerecord::base.shared_connection = activerecord::base.connection  factorygirl.reload 

this fresh setup of capybara-poltergeist rails app, check difference between , versions? (i'm lazy ^_^ )
