Sin embargo encontre este excelente y provocativo articulo, llamado Test Driven Design: Using Mocks And Tests To Design Role-Based Objects. Lo lei todo (s lei todo esta vez, nada de skip) y quiero decirles que esto parece ser el futuro. Realmente le falta un poco mas, pero podriamos decir que con ideas de BDD / Cucumber, podriamos crear un tipo de metodologia para transformar un requerimiento en pruebas y mocks.

Feature (estilo Cucumber) + TDD Mock driven Interface Design + Hand Coding = Software

Hay que probarlo, pero esto realmente sirve para crear robots web. Cuando yo creo un robot web los pasos son:

1. Manualmente try and test el URL
2. Crear código esqueleto (framework)
3. Agregar lógica de negocio (Business Logic)
4. Crear prueba / test
5. Ejecutar pruebas / test

Con esto, se cambia a:

1. Crear prueba / test
2. Crear funcionalidad
3. Crear código esqueleto
4. Agregar lógica de negocio
5. Ejecutar pruebas

Ademas, existe hasta un REST stack para Mono: http://code.google.com/p/servicestack/

Super interesante.

Selenium RC 

Cucumber Documentation 

First you need to download Selenium RC and install it. Create this batch in C:Program Files(your selenium RC dir)

@ECHO OFF
java -jar selenium-server.jar
REM -browserSessionReuse
REM -proxyInjectionMode

Install Cucumber for IronPython

Read this documentation on how to install Cucumber with IronPython 

Be sure to have icucumber.bat, mine is in IronPython bin

@ECHO OFF
REM This is to tell IronRuby where to find gems.
SET GEM_PATH="C:ironruby-0.9.0libIronRubygems1.8"
@"C:ironruby-0.9.0binir.exe" "C:ironruby-0.9.0bincucumber" %*

• Install Notepad++, so you can edit those pesky ruby files
• install
  • gem install Selenium
  • gem install watir

Create Cucumber features and steps

insertnew.feature

 Feature: Insert New Contact
  In order to insert a new contact
  As a MediaWiki Authenticated user
  I want to fill the form fields

  Scenario Outline: Add Contact
    Given I am on the Add Contact Form
    And I entered user <FirstName>
    And last name <LastName>
    And e-mail <Email>
    And bio <Bio>
    And birthday <Birthday>
    When I click Save Page
    Then I should wait for the page to display the results

  Examples:
    |FirstName | LastName | Email | Bio | Birthday |
    | Cliff      | Heath      | ch@google.com     |   http://www.google.com  | 29 |

insertnew_steps.rb

Given /^I am on the Add Contact Form$/ do
  @browser.open(‘http://myWebServerApp&#8217;)
end    
    
Given "I entered user $value" do |value|
  @browser.type "input_2", value
end

Given "last name $value" do |value|
  @browser.type "input_3", value
end

Given "e-mail $value" do |value|
  @browser.type "input_4", value
end

Given "bio $value" do |value|
  @browser.type "input_5", value
end

Given "birthday $value" do |value|
  @browser.type "input_6_day", value
end

When /I click Save Page/ do
  @browser.click "wpSave"  
  @browser.wait_for_page_to_load
end

Then /wait for the page to display/ do

end

env.rb

require ‘spec/expectations’
require ‘selenium’

# "before all"
browser = Selenium::SeleniumDriver.new("localhost", 4444, "*chrome", "http://www.google.com&quot;, 15000)

Before do
  @browser = browser
  @browser.start
end

After do
  @browser.stop
end

# "after all"
at_exit do
  browser.close rescue nil
end

How to test

2. Run feature: icucumber features –no-color

Tiene un enlace a Introducing BDD, cual me parece completo y sencillo de entender.

Thomas Lundström tiene mas información y adicionalmente como integrar Cucumber en .NET usando IronRuby 0.9

Aqui hay una herramienta semi TDD y BDD (lo llaman BDT), Pyccuracy. Algo abstracto.
