Rubis Watir Gem, Temporisation sur l'entrée de formulaire

Question

Je pratique le webscraping en utilisant les gemmes Watir, Mechanize et Nokigiri.

Je rencontre un problème avec mon script Watir. Mon plan est d'obtenir une liste des prix des vols via http://tripadvisor.com/. Lorsque je lance le script, le navigateur Chrome s'ouvre comme il se doit, le script remplit les premières parties du formulaire, l'origine et la destination, puis s'arrête. Voici le message d'erreur que je reçois:

This code has slept for the duration of the default timeout waiting for an Element to be present. If the test is still passing, consider using Element#exists? instead of rescuing UnknownObjectException

    from watir_test.rb:8:in `<main>' </ 

Voici mon code:

require 'watir' 

browser = Watir::Browser.new 

browser.goto('https://tripadvisor.com/CheapFlightsHome') 
browser.input(name: 'orig').send_keys('Boston, MA - Logan International Airport (BOS)') 
browser.input(name: 'dest').send_keys('Milan, Italy - All Airports (MIL)') 
browser.input(name: 'rt_leaveday').send_keys('1') 
browser.input(name: 'rt_leavemonth').send_keys('06/2017') 
browser.input(name: 'retday').send_keys('30') 
browser.input(name: 'leavemonth').send_keys('06/2017') 
browser.input(value: 'Search Flights').click 
puts browser.url 
browser.quit

Il ne peut pas valeur définie sur le rt_leaveday ou rt_leavemonth parce qu'ils sont entrées cachées. Mais vous pouvez exécuter un script pour cliquer sur dateselector:

require 'watir' 

browser = Watir::Browser.new 

browser.goto('https://tripadvisor.com/CheapFlightsHome') 
browser.text_field(name: 'orig').set('Boston, MA - Logan International Airport (BOS)') 
browser.text_field(name: 'dest').set('Milan, Italy - All Airports (MIL)') 
browser.execute_script('document.querySelector(".in_date").click()') 
browser.execute_script('document.querySelector(".day_28").click()') 
browser.execute_script('document.querySelector(".out_date").click()') 
browser.execute_script('document.querySelector(".day_2").click()') 
browser.span(id: "CHECK_FARES_BUTTON").fire_event :click 
puts browser.url 
browser.quit
