When generating specs with :

rails g controller Home index

A spec is generated with the older object.should syntax

require 'spec_helper'

describe HomeController do   
  describe "GET 'index'" do
    it "returns http success" do
      get 'index'
      response.should be_success
    end
  end  
end

Is it possible to configure the generator to use the expect syntax instead?

Desired output:

require 'spec_helper'

describe HomeController do

  describe "GET 'index'" do
    it "returns http success" do
      get 'index'
      expect(response).to be_success
    end
  end

end

in config/application.rb:

config.generators do |g|
  g.test_framework :rspec, fixture: true
  g.fixture_replacement :factory_girl, dir: 'spec/factories'
  g.view_specs false
  g.stylesheets = false
  g.javascripts = false
end
