Forum: Ruby Simple script not working

Hi,

require 'rubygems'
require 'watir-webdriver'

children=[]
count=0
fact=0
5.times do
children<<Thread.new do
    1.times do
    fact+=1
    begin
    br=Watir::Browser.new :ie
    br.goto('some-site')
    br.link(:text,'Sign In').click
    count+=1 if br.text_field(:id,'username').exist?
ensure
    br.close
end
    end
end
end
children.each do |c|
    c.join
end
puts "fact: #{fact} count: #{count}"

Giving me following error:

It looks like your browser can't establish a connection. Firewall?

I can see that it opens few ie window and then throws the error. Even on 
irb i can atart a browser and go to url etc.. By the way if its the case 
of firewall.. Then how can I check that?

You may also fall victim of a connection count restriction as is
usually present in client Windows systems.

Check firewall logs.  Where they reside depends on the firewall used.

Kind regards

no logs I found, i mean its blank.

I've also seen that error before when the browser is closed in the 
middle of doing something. Maybe "br.close" is triggering while the 
thread is still doing something?

How can it be triggered without reason?

How many browsers can you use like this before you experience the error? 
If it's consistent then as Robert said, it might well be the connection 
count. Don't forget you may have other processes running which can all 
add up.

With regard to the browser closing, it's more of a direction to look in 
than a specific pointer... try closing the browser manually during 
execution and see if the error is exactly the same. You could also add a 
rescue and log to see whether every subsequent browser window 
experiences the same error.
