Hi all,

I am getting the below error when I try to run my test case. I have  
already started selenium RC server (port:4444)… Also I have specified  
" 127.0.0.1 localhost " in /etc/hosts …

:ruby test1.rb  
Loaded suite test1  
Started  
E  
Finished in 0.022698 seconds.

1. Error:  
testfestool(Test1):

The code am using for connection is:

require “rubygems”  
require “selenium/client”  
require “test/unit”

class Test1 \< Test::Unit::TestCase  
def setup  
@verification\_errors = []

```
 @selenium = Selenium::Client::Driver.new \
    :host => "http://127.0.0.1",
    :port => 4444,
    :browser => "*firefox",
    :url => "http://www.google.com/",
    :timeout_in_second =>60

 #start browser session
 @selenium.start
 @selenium.set_context("test1")

```

end

def teardown  
@selenium.stop  
assert\_equal [], @verification\_errors  
end

Let me know if you need any other additional information. Thanks for  
your help in advance 🙂 …
