Ruby Selenium Webdriver - 不會點擊？

Question

剛開始使用ruby + webdriver，我做了一個小腳本，我想知道爲什麼腳本不會點擊web元素然後輸入值？

require 'rubygems' 
require 'selenium-webdriver' 

class Standard_webdriver_ruby 
    driver = Selenium::WebDriver.for :firefox 
    driver.get 'http://demoqa.com/contact/' 
    driver.manage.window.maximize 
    wait = Selenium::WebDriver::Wait.new(:timeout => 5) 

    fillFormData = Array.new('rob', 'rob@hotmail.co.uk', 'whoop', 'Message content') 

    name_field = driver.find_element :css => ('#wpcf7-f375-p28-o1 > form > p:nth-child(2) > span > input') 
    name_field.click 
    name_field.send_keys(fillFormData[0]) 
    email_field = driver.find_element :css => '#wpcf7-f375-p28-o1 > form > p:nth-child(3) > span > input' 
    email_field.click 
    email_field.send_keys(fillFormData[1]) 
    subject_field = driver.find_element :css => '#wpcf7-f375-p28-o1 > form > p:nth-child(4) > span > input' 
    subject_field.click 
    subject_field.send_keys(fillFormData[2]) 
    message_field = driver.find_element :css => '#wpcf7-f375-p28-o1 > form > p:nth-child(5) > span > textarea' 
    message_field.click 
    message_field.send_keys(fillFormData[3]) 
end

你錯誤地實例化數組：

# incorrect 
fillFormData = Array.new('rob', 'rob@hotmail.co.uk', 'whoop', 'Message content') 

# correct 
fillFormData = ['rob', 'rob@hotmail.co.uk', 'whoop', 'Message content'] 

# correct, ruby-way 
fillFormData = %w[rob rob@hotmail.co.uk whoop Message\ content] 

Array#new預計大小或數組作爲參數。
