Testing generators with cucumber and aruba

I've just released a gem on github and I wrote integrations test with aruba gem. However I can't run features because it behaves differently from command line.

If i run the features rails can't find my generator, if I repeat the same steps on the commandline they run flawlessly.

This is a failing feature

Background: A new rails application has been created with my gem
  Given a rails application named "my_app" exists
  And this gem is installed in that application

@announce
Scenario: Installation using default values
  When I successfully run `rails generate google_authentication:install`
  # this is needed because rails g returns 0 when can't find the generator
  And the output should not contain "Could not find generator"

And this is the code which implements background steps

Given /^a rails application named "([^\"]*)" exists$/ do |app_name|
  @app_name = app_name
  Given "I successfully run `rm -rf #{app_name}`" # added to ensure that the working directory is clean
  And "a directory named \"#{app_name}\" should not exist"
  And "I successfully run `rails new #{app_name}`"
  And "I cd to \"#{app_name}\""
end

When /^this gem is installed in that application$/ do
  gempath = File.expand_path('../../../', __FILE__)
  Given "I append to \"Gemfile\" with \"gem 'gem-name', :path => '#{gempath}'\""
  And "I successfully run `bundle check`"
end

I tried to debug and I found that if I change the bundle check command with bundle install and I capture the output, my gem is not listed in the bundle. As a consequence if I write a rails g --help step my generator is not there. However devise gem and generators are there (devise is listed as requirement in my gem. So it seems that bundler/rails is not loading all inside aruba steps.

I think that this is a bug with Aruba or Bundler, I opened an issue for aruba but still no answers.

Full code is on Github

Last thing I've already seen and tried this solution but with no luck

Instead of all of those steps you wrote which are a bit deprecated in cucumber.

Try something like this:

Given /^a rails application named "([^\"]*)" exists$/ do |app_name|
  FileUtils.mkdir_p("tmp")
  system("rm -rf tmp/#{app_name}")
  system("rails new tmp/#{app_name}")
  system("ln -s ../../../lib/generators tmp/#{app_name}/lib")
  @current_directory = File.expand_path("tmp/#{app_name}")
end

You have to create a link to the directories. It makes more sense than doing bundle install which you shouldn't attempt testing using cucumber.
