Include helper not works

问题:

I'm trying to include some helpers to my test but I can't make that it works. I got the following error:

/home/edu/.rvm/rubies/ruby-1.9.3-p392/bin/ruby -S rspec ./spec/features/customers_spec.rb ./spec/features/login_spec.rb ./spec/features/products_spec.rb ./spec/features/suppliers_spec.rb
        /home/edu/Desktop/rails_proyects/gg/spec/support/features.rb:2:in `block in <top (required)>': uninitialized constant MyHelp (NameError)
          from /home/edu/.rvm/gems/ruby-1.9.3-p392@gg/gems/rspec-core-2.14.6/lib/rspec/core.rb:120:in `configure'
          from /home/edu/Desktop/rails_proyects/gg/spec/support/features.rb:1:in `<top (required)>'

I have this:

# spec/support/features/session_helper.rb
module MyHelp
  module SessionHelpers
    ...
    def sign_in
      ...
    end
  end
end

# spec/support/features.rb
RSpec.configure do |config|
  config.include MyHelp::SessionHelpers, type: :feature
end

I'm using it here:

# spec/features/login_spec.rb
require 'spec_helper'

feature "Login" do
  scenario "with valid credentials" do
    user = create(:user)
    sign_in user.email, user.password
    page.should have_content(I18n.t('layouts.header.exit', locale: 'es'))
  end
end

I'm using:

rspec (2.14.1)
rspec-core (2.14.6, 2.14.5) 
rspec-expectations (2.14.3, 2.14.2) 
rspec-mocks (2.14.4, 2.14.3) 
rspec-rails (2.14.0)

ruby 1.9.3p392 
rails 3.2.13

Can someone help me with this? thank you.

It looks like you just need to require the new helper before you try to use it in spec/support/features.rb

require Rails.root.join('spec/support/features/session_helper')

Also, it's best practice to have your class/module match the file name, so either the file should be pluralized, or the helper singularized.
