A quick hack to check there is internet before running some testcases

is_there_internet.rb

module IsThereInternet
  
  def is_there_internet?
    if $IS_THERE_INTERNET.nil?
      $IS_THERE_INTERNET = system "ping -q -c 1 google.com 1> /dev/null"
    end
    $IS_THERE_INTERNET
  end
  
  # test "something" do
  #   requires_internet! do
  #     # my test case here
  #   end
  # end
  #
  def requires_internet!
    if is_there_internet?
      yield
    else
      flunk "this test needs to be run when there is internet"
    end
  end
  
end
