# Tested With
# android-server-2.21.0.apk
# selenium-dotnet-2.21.0
# selenium-webdriver (2.21.2) Gem

require "rubygems"
require "selenium-webdriver"

driver = Selenium::WebDriver.for(:remote, :url => "http://localhost:8080/wd/hub", :desired_capabilities => Selenium::WebDriver::Remote::Capabilities.android)
driver.navigate.to "http://www.google.com"
element = driver.find_element(:name, 'q')
search_term = "F1"
element.send_keys search_term

sleep 5
element = driver.find_element(:name, 'q')
value = element.attribute("value")
raise "Expected #{value} to equal #{search_term}" if value != search_term

# Fails with :Expected F! to equal F1
