用Java不是问题,但如何用ruby制作呢？

require 'rubygems'
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :firefox
driver.get "http://google.com"

element = driver.find_element :name => "q"
element.send_keys "Cheese!"
element.submit

puts "Page title is #{driver.title}"

wait = Selenium::WebDriver::Wait.new(:timeout => 10)
wait.until { driver.title.downcase.start_with? "cheese!" }

puts "Page title is #{driver.title}"
driver.quit

如果这不是一个选项,你可以尝试this SO post的建议,虽然它需要在Ruby / Rails之上的一些Javascript.

看来wait.until已经/已经被淘汰了.新的建议过程,它寻找页面有你知道的元素将在那里：

expect(page).to have_selector '#main_div_id'
