Testing webrat and = in form values

require 'webrat'
require 'webrat/adapters/mechanize'
include Webrat::Methods

TESTURL = "http://www.directionless.org/webrat-test.pl"

Webrat.configure do |config| 
  config.mode = :mechanize
end

class Webrat::Form
  def self.query_string_to_params(query_string)
    # Bug is here. This splits to an array and only takes the first
    # and last. While we need everything in between.
    case Webrat.configuration.mode
    when :rails
      parse_rails_request_params(query_string)
    when :merb
      ::Merb::Parse.query(query_string)
    when :rack, :sinatra
      Rack::Utils.parse_nested_query(query_string)
    else
      query_string.split('&').map {|query| { query.split('=',2).first => query.split('=',2).last }}

puts "First, webrat:\n\n"
visit TESTURL
response = click_button
puts response.body


puts "\nAnd now mechanize:\n\n"
mresponse = Mechanize.new.get(TESTURL).forms.first.submit
puts mresponse.body

That TESTURL is a simple form that checks if the default values were actually submitted, and outputs. Running this script, with webrat 0.7.2 and mechanize 1.0.0 results in:

First, webrat:

fourth:  correct
   expected: email@example.com
   got: email@example.com
third:  WRONG
   expected: qwerty=
   got: qwerty
first:  correct
   expected: qwerty123
   got: qwerty123
second:  WRONG
   expected: 123=345
   got: 345

And now mechanize:

first:  correct
   expected: qwerty123
   got: qwerty123
second:  correct
   expected: 123=345
   got: 123=345
third:  correct
   expected: qwerty=
   got: qwerty=
fourth:  correct
   expected: email@example.com
   got: email@example.com
