Run tests in multiple browsers with ruby + watir-w

Currently I use the parallel profile in cucumber.yml to load an environment specific file and hooks.rb to set the browser. I run my tests using 'parallel_cucumber features'. There is not much in my hooks.rb file:

Before do
  @browser = Watir::Browser.new :firefox
end

After do 
  @browser.close
end

The profile looks like this:

parallel: FIG_NEWTON_FILE=local.yml --no-source --color --format pretty

Is there a way to change my hooks.rb file so that all features run against a set of browsers (firefox, chrome, safari)? Is possible to pass the file name or environment through the command line?

You can definitely pass the environment name through the command line. Check out my env.rb file:

case ENV['BROWSER']
  when 'ff', 'Firefox'
    browser = Selenium::WebDriver.for :firefox
    browser_name = 'Firefox'
  when 'chrome'
    browser = Selenium::WebDriver.for :chrome
    browser_name = 'Chrome'
  when 'debug'
    debug_profile = Selenium::WebDriver::Firefox::Profile.new
    debug_profile.add_extension "firebug-1.9.1-fx.xpi"
    browser = Selenium::WebDriver.for :firefox, :profile => debug_profile
    browser_name = 'Firefox (Firebug)'
  when 'mobile'
    mobile_profile = Selenium::WebDriver::Firefox::Profile.new
    mobile_profile['general.useragent.override'] = "Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en)
      AppleWebKit/420+ (KHTML, like Gecko) Version/3.0
      Mobile/1A535b Safari/419.3"
    browser = Selenium::WebDriver.for :firefox, :profile => mobile_profile
    browser_name = 'Mobile'
  when 'headless'
    headless_profile = Headless.new
    headless_profile.start
    browser = Selenium::WebDriver.for :firefox
    browser_name = 'Firefox'
  else
   browser = Selenium::WebDriver.for :firefox
   browser_name = 'Firefox'
end

if URLS[ENV['URL']].nil?
  environment = 'dev'
  url = 'http://' + URLS['dev']
  domain = URLS['dev']
else
  environment = ENV['URL'].upcase
  url = 'http://' + URLS[ENV['URL']]
  domain = URLS[ENV['URL']]
end

if ENV['CLIENT'].nil?
  client = 'user/password'
else
  client = ENV['CLIENT']
end

puts "Browser      " + browser_name
puts "URL          " + url
puts "Environment: " + environment
puts "Client:      " + client
puts "Domain:      " + domain

test_env = {   :browser => browser,
               :browser_name => browser_name,
               :url => url,
               :env => environment,
               :client => client,
               :login => nil,
               :domain => domain }

Now when I run cucumber, I call the environment by doing:
