Watir/Rspec Browser Loop - ruby

Question

I need some help using multiple browsers in a loop with Watir/Rspec.
My Goal is to:
Go to Google.ca
Quickly search something
Close browser.
Loop steps 1-3 using a different browser.
I can get this to work with using Watir, but do not know how to get this to work with Rspec.
Watir (working code):
require 'watir-webdriver'
require 'rspec'
browsers = [:ff, :chrome]
browsers.map do |x|
$browser = Watir::Browser.new x
$browser.goto('http://www.google.ca')
$browser.text_field(:id, 'gbqfq').set 'Juventus'
$browser.send_keys :enter
$browser.close
end #End loop
Rspec (not working):
require 'watir-webdriver'
require 'rspec'
browsers = [:ff, :chrome]
browsers.map do |x|
$browser = Watir::Browser.new x
$browser.goto('http://www.google.ca')
describe 'loop' do
it 'does something' do
$browser.text_field(:id, 'gbqfq').set 'Juventus'
$browser.send_keys :enter
$browser.close
end
end #End describe
end #End loop
This is what happens with the code above:
Loads Firefox
Goes to Google
Loads Chrome
Goes to Google
Searches on Chrome
It seems when I include Rspec describe the loop does not work as I had intended it to.

Answer 1

Finally figured it out :)
Here is the code for anyone that wants to do multiple browser testing without making different specs for each browser.
require 'watir-webdriver'
require 'rspec'
browsers = [:ff, :chrome]
browsers.map do |x|
describe 'Browser' do
before(:all) do
#browser = Watir::Browser.new x
end
it 'goes to Google.ca' do
#browser.goto('http://www.google.ca')
end
it 'searches' do
#browser.text_field(:id, 'gbqfq').when_present(3).set 'Juventus'
#browser.send_keys :enter
sleep 0.5 #roughly takes 0.5s for the images to load.
end
it 'closes browser' do
#browser.close
end
end #end describe
end #end loop
I think for this to work properly you need to initialize the browser after describe whereas before I was initializing the browser before describe
