Subject: Ruby and selenium for a newbie

Hi

I am looking at automation using selenium with the ruby api, and am
having a little problem.

im not sure other than making @selenium into a global variable how can i
use it across multiple files.

so i have three files:

start.rb
--------
require 'test'

setup.rb
--------
require "selenium"
require "test/unit"

  class Setup1 < Test::Unit::TestCase

    def setup
      @verification_errors = []
      if $selenium
        @selenium = $selenium
      else
        @selenium = Selenium::SeleniumDriver.new("localhost", 4444,
"*firefox", "http://www.google.com/", 10000);
        @selenium.start
      end
    end

    def teardown
      @selenium.stop unless $selenium
      assert_equal [], @verification_errors
    end
  end

test1.rb
--------
require "selenium"
require "test/unit"
require 'setup1'

  class Test1 < Test::Unit::TestCase

    def test_1
      @selenium.open("/")
      @selenium.type "q", "selenium rc"
      @selenium.click "btnG"
      @selenium.wait_for_page_to_load "30000"
      assert @selenium.is_text_present("Results * for selenium rc")
    end
  end

this runs, but stops when it reaches @selenium.open("/").

NoMethodError: private method `open' called for nil:NilClass

As Test1 is already a subclass of TestCase, I am unable to make it a
subclass of Setup1.

I have read about modules, and amended the code with "include Setup",
but it appears I have no control over it running the Setup method each
time a new Test is added.

Essentially, I want to know how reference variables across mutiple
files, and as @selenium is an intsance variable, does this mean its only
accessibly by objects which are created from the Setup1 class.

And I get the impression $global variables are a no no, but on the fact
that the @selenium value(browser url) wont change, wouldnt it be ok to
set it as a global?

Please help!
