ruby - Javascript trigger when using poltergiest/capybara outside of rails -


i'm using capybara, rspec , poltergeist, outside of rails, run headless integrations tests. scenario that, there 2 select fields. if select value in first select field, 2nd select field populated based on value of first select field. if run spec using poltergeist in mac osx, spec works. in ubuntu, fails, seems 2nd select field not populated. have js: true on specs.

here's spec_helper.rb:

require 'capybara/poltergeist' require 'capybara' require 'capybara/rspec' require 'pry' require 'support/session_helper' rspec.configure |config|    config.include capybara::dsl   config.include capybara::poltergeist   config.include sessionhelper    capybara.run_server = false   capybara.default_driver = :poltergeist   capybara.javascript_driver = :poltergeist   capybara.app_host = "http://vps-staging.dropmysite.com"    options = { js_errors: false }   capybara.register_driver :poltergeist |app|     capybara::poltergeist::driver.new(app, options)   end    config.expect_with :rspec |expectations|      expectations.include_chain_clauses_in_custom_matcher_descriptions = true   end    config.mock_with :rspec |mocks|     mocks.verify_partial_doubles = true   end  end

edit adding failing spec

require 'spec_helper'  feature 'vps-staging', js: true   background     visit '/'   end    let(:timestamp) { time.now.strftime('%y-%m-%d_%h-%m-%s') }     feature 'create private server'     background       sign_in 'blahblah@blahblah.com'     end      'successfully creates server'       find(:xpath, "//a[@href='/en/private_servers/new']").click        directory_field = all(".tagit-new")[0].find("input")       select 'ubuntu', from: 'distribution'       select '15.04', from: 'version'       fill_in 'private_server_profile_name', with: "auto test #{timestamp}"       directory_field.set "/home"       click_button 'save'        visit '/en/dashboard'        expect(page.text).to have_content "auto test #{timestamp}"     end   end end

edit thing found out that, bug happens on phantomjs version 1.9.8 , below. 2.0 works fine.

as tom walpole pointed out, updating poltergeist 1.6.0 1.7.0 fixed of problem still need tweak bit solve problem. did create js file hold polyfill , edit spec_helper.rb , tell poltergeist use options, extensions , include polyfill.js changing code from

options = { js_errors: false }   capybara.register_driver :poltergeist |app|     capybara::poltergeist::driver.new(app, options)   end

to

options = { js_errors: false, extensions: ["spec/support/polyfill.js"] }   capybara.register_driver :poltergeist |app|     capybara::poltergeist::driver.new(app, options)   end

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
