How to execute two or more executions scripts simultaneously on a same URL using WATIR

Question

I am using watir 2.0.1,currently if a script is running on url say ABC.com in one tab for IE browser and if i opens same url ABC.com in other tab or new instance of the browser then the execution will switch to this new tab open. Because of this i am not able to execute multiple scripts/executions on same URL

Here is the code for Script1.rb in Project1,

require 'watir'
browser = Watir::Browser.new
browser.goto 'https://example.com'
browser = Watir::Browser.attach(:title, /ABC Application/)
browser.button(:text,"Register").click
sleep 2
browser.text_field(:id,"First_Name").set "Script_1_FirstName"
sleep 2
browser.text_field(:id,"Last_Name").set "Script_1_LastName"

and so on...

While Script1 is filling the register form for ABC application in Browser instance1,at the same time(Say after Script1 Enters First Name, i will trigger Script2.rb for some basic validations of the register form page.

Here is the code for Script2.rb in Project2,

require 'watir'
browser1 = Watir::Browser.new
browser1.goto 'https://example.com'
browser1 = Watir::Browser.attach(:title, /ABC Application/)

//At this time Script2 will execute properly in IE Instance2 as there is
//no Register button at IE instance1(Because Script1 is already on
//Register form page) 

browser1.button(:text,"Register").click

//The movement Register form opens in IE instance2,Script1 finds same page
//elements on IE instance2 so currently Script1 is automatically start its
//execution on IE instance2 which will affect Script2 Execution.     

if(browser1.text_field(:id,"First_Name").text.include("")
puts "First name field is blank by default"
else
raise "First name field is not blank by default"

if(browser1.text_field(:id,"Last_Name").text.include("")
puts "Last name field is blank by default"
else
raise "Last name field is not blank by default"

The problem is with each script attaching to a browser, which may or may not be the one opened earlier in the script.

The line:

browser = Watir::Browser.attach(:title, /ABC Application/)

Is saying to attach to the first browser with a title that includes "ABC Application". If all of the scripts are looking for this title, they will all be attaching to the same browser.

The solution is to use the browser that was opened by the script. This should simply require deleting this Watir::Browser.attach line. The browser variable would then continue to point to the browser it opened in browser = Watir::Browser.new.
