Cucumber-Rails brings Cucumber to Rails2 and Rails3. It contains 2 generators - one for bootstrapping your Rails app for Cucumber, and a second one for generating features.

Cucumber-Rails also contains Cucumber Step Definitions that wrap Capybara or Webrat, giving you a head start for writing Cucumber features against your Rails app.

Before you can use the generator, add the necessary gems to your project’s Gemfile as follows:

gem 'capybara'
gem 'database_cleaner'
gem 'cucumber-rails'
gem 'cucumber'
gem 'rspec-rails'
gem 'spork'
gem 'launchy'    # So you can do Then show me the page

Then install the gems by running:

bundle install

Learn about the various options:

ruby script/rails generate cucumber:install --help

Finally, bootstrap your Rails app, for example:

ruby script/rails generate cucumber:install --rspec --capybara

Before you can use the generator, install the gem by running:

gem install cucumber-rails

Learn about the various options:

ruby script/generate cucumber --help

Finally, bootstrap your Rails app, for example:

ruby script/generate cucumber --rspec --capybara

IMPORTANT: Only do this if you are new to Cucumber. We recommend you write your Cucumber features by hand once you get the hang of it.

Example:

ruby script/rails generate cucumber:feature post title:string body:text published:boolean
ruby script/rails generate scaffold post title:string body:text published:boolean
rake db:migrate
rake cucumber

Example:

ruby script/generate feature post title:string body:text published:boolean
ruby script/generate scaffold post title:string body:text published:boolean
rake db:migrate
rake cucumber
