How to use Selenium RC in Rails

Hi,

I am trying to use Selenium RC in my rails application. I first install selenium RC ruby client (>gem install selenium-client). Then create a "selenium_test.rb" in libs folder. In the file, I create a class "SeleniumTest".

# libs/selenium_test.rb

require "selenium-client"

class SeleniumTest   attr_reader :browser

  def initialize     @browser = Selenium::Client::Driver.new \         :host => "localhost",         :port => 4444,         :browser => "*firefox",         :url => "http://www.google.com",         :timeout_in_second => 60    end   end

In a controller file, I create an instance of this class.

o=SeleniumTest.new

When I run rails, it returns an error:

LoadError in LoginsController#create no such file to load -- selenium-client

I tried to add the following require settings in /config/ development.rb. No helpful.

require "rubygems" gem "selenium-client", ">=1.2.17" require "selenium/client"

I am new in Rails. It seems a quite simple task. I have some third- party library and want to use in my code. In C#, I just add the reference, then specify its namespace in the top of the file. It is actually similar in Ruby code. But for Rails, I do not know how to reference external lib. Could someone here help me? Really appreciate.
