Sinatra

Webrat

You can use Cucumber with Sinatra and Webrat!

Just make sure you have a features/support/env.rb file with the following:

app_file = File.join(File.dirname(__FILE__), *%w[.. .. app.rb])
require app_file
# Force the application name because polyglot breaks the auto-detection logic.
Sinatra::Application.app_file = app_file

require 'spec/expectations'
require 'rack/test'
require 'webrat'

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

class MyWorld
  include Rack::Test::Methods
  include Webrat::Methods
  include Webrat::Matchers

  Webrat::Methods.delegate_to_session :response_code, :response_body

  def app
    Sinatra::Application
  end
end

World{MyWorld.new}

You may have to set the app_file in your app file. Otherwise Sinatra (at least version 0.9.1.1) won’t find the views or layouts (see this irc log) e.g.,

# In your main application file
configure do
  set :views, "#{File.dirname(__FILE__)}/views"
end

Sinatra/Test

You can also use Cucumber with Sinatra using Sinatra’s built-in testing setup and Test Harness_. Make sure you have something like the the following, tailored to Test::Unit, RSpec, Bacon or Test::Spec, in your features/support/env.rb.

require File.dirname(__FILE__) + "/../../your_sinatra_app"

# RSpec matchers
require 'spec/expectations'

# Required for RSpec to play nice with Sinatra/Test
require 'spec/interop/test'

# Sinatra/Test
require 'sinatra/test'

Test::Unit::TestCase.send :include, Sinatra::Test

World do
  Sinatra::TestHarness.new(Sinatra::Application)
end

Rack-Test

You can also use Cucumber with Sinatra using Bryan Helkamp’s rack-test and Webrat. You can check out the rspec examples in the hancock application. Something like the following should be setup in your features/support/env.rb.

require File.expand_path(File.dirname(__FILE__)+'/../../spec_helper')
require 'haml'

MyApp::App.set :environment, :development

World do
  def app
    @app = Rack::Builder.new do
      run MyApp::App
    end
  end
  include Rack::Test::Methods
  include Webrat::Methods
  include Webrat::Matchers
end
