Sinatra

Cucumber-Sinatra Generator

The Cucumber-Sinatra gem will generate a features directory structure and features/support/env.rb in your Sinatra project pre-configured for testing with Cucumber, RSpec, and Capybara.

This gem is inspired by the Cucumber-Rails generator.

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 'rspec/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). You also need to specify the public directory, even if you’re on default, otherwise stylesheets and javascripts won’t be available to your Cucumber session e.g.,

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

# Required for RSpec to play nice with Sinatra/Test
require 'rspec/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
