Problem using Basic Auth in WebUnit

I am beginning my first real Ruby app and having some problems
understanding how to use basic auth in webunit.

I have created a test case like so:

require ‘webunit/webunit’

class LoggerTest < WebUnit::TestCase

def setup
		super
		$DEBUG=true
	@url

="http://myhostname:10405/mbean?objectname=Portal:name=JVM"
end

 def testAuthenticate	 		
 		user="fred"
 		pass="opensesame"
		response = WebUnit::Response::get( @url , nil,

%w(user pass) )
assert_title( “MX4J - MBean View”, response )
puts response.inspect()
end
end

test = LoggerTest.new(“testAuthenticate”)
test.setup
test.testAuthenticate

Can anyone tell me what %w(user pass) does?

but the program fails with the following (with debug enabled)

C:/ruby/lib/ruby/site_ruby/webunit/response.rb:94: undefined methodto_str’ for nil’ (NameError)
C:/ruby/lib/ruby/site_ruby/webunit/response.rb:94: undefined methodto_str’ for nil’ (NameError)

C:/ruby/lib/ruby/1.6/net/protocol.rb:630: @buffer << @socket.sysread(

Does this error mean anything to anyone?

Has anyone else got basic auth working in webunit?
