#
#  The TCP-protocol test.
#
#  This object is instantiated if the parser sees a line such as:
#
###
### foo.vm.bytemark.co.uk must run tcp on 22 with banner 'ssh' otherwise 'ssh fail'.
###
#
#  The specification of the port is mandatory, the banner is optional.
#
class TCPTest < ProtocolTest


  #
  # Constructor
  #
  # Ensure we received a port to run the TCP-test against.
  #
  def initialize( line )
    raise ArgumentError, "Missing port" unless ( line =~ /on\s+([0-9]+)/ );
