How do I use selenium with Ruby? - ruby

Question

I made some tests with the Firefox Selenium and then had it exported to Ruby. Although the tests all ran fine in Firefox, I am having trouble running the same suite in Ruby.
I tried to run one of the example programs they have and I also get the same connection refused error. Here is the error I got when trying to run their google_test suite.
tellingsen$ ruby google_test.rb
Loaded suite google_test

test_page_search(ExampleTest):

Can someone help me with this?

EDIT
Here is the google_test.rb that I tried
#!/usr/bin/env ruby
#
# Sample Test:Unit based test case using the selenium-client API
#
require "test/unit"
require "rubygems"
gem "selenium-client", ">=1.2.18"
require "selenium/client"
class ExampleTest < Test::Unit::TestCase
attr_reader :browser
def setup
#browser = Selenium::Client::Driver.new \
:host => "localhost",
:port => 4444,
:browser => "*firefox",
:url => "http://www.google.com",
:timeout_in_second => 60
browser.start_new_browser_session
end
def teardown
browser.close_current_browser_session
end
def test_page_search
browser.open "/"
assert_equal "Google", browser.title
browser.type "q", "Selenium seleniumhq"
browser.click "btnG", :wait_for => :page
assert_equal "Selenium seleniumhq - Google Search", browser.title
assert_equal "Selenium seleniumhq", browser.field("q")
assert browser.text?("seleniumhq.org")
assert browser.element?("link=Cached")
end
end

Answer 1

I figured it out after a few hours of searching on forums and through google.
What I needed to do was have the selenium server running for it to work. I was able to download it from this site http://seleniumhq.org/download/ (current: Selenium RC February 23, 2010 1.0.3).
From there I opened up a new terminal and did
cd Downloads/selenium-remote-control-1.0.3/selenium-server-1.0.3
java -jar selenium-server.jar
Then ran my ruby generated script with another terminal window
ruby google_test.rb
And it worked!

Answer 2

This is Selenium Webdriver example for simple google search
Save as google_search.rb
require "selenium-webdriver"
require "test/unit"
class GoogleSearch < Test::Unit::TestCase
def setup
#driver = Selenium::WebDriver.for :firefox
#base_url = "http://www.google.com/"
#driver.manage.timeouts.implicit_wait = 30
#verification_errors = []
end
def teardown
#driver.quit
assert_equal [], #verification_errors
end
def test_google_search
#driver.get(#base_url)
#driver.find_element(:name, "q").clear
#driver.find_element(:name, "q").send_keys "Thiyagarajan Veluchamy"
#driver.find_element(:name, "btnK").click
end
def element_present?(how, what)
#driver.find_element(how, what)
true
rescue Selenium::WebDriver::Error::NoSuchElementError
false
end
def verify(&blk)
yield
rescue Test::Unit::AssertionFailedError => ex
#verification_errors << ex
end
end
$ruby google_search.rb

Here is a much simpler version of the script:
require "selenium-webdriver"
#driver = Selenium::WebDriver.for :chrome
#base_url = "http://www.google.com/"
#driver.get(#base_url)
#driver.find_element(:name, "q").send_keys "Stack Overflow"
Methods available on the #driver object can be found here: http://selenium.googlecode.com/svn/trunk/docs/api/rb/Selenium/WebDriver/Driver.html
find_element gives you access to the Element class. Methods available on the Element class can be found here:
