Generate a new project without the included testing and with a postgres database:
```bash
rails new MyApp -T --database=postgresql
```

Add rspec, capybara, factory_girl, launchy and database cleaner to gemfile:
```ruby
group :development, :test do
  gem 'rspec-rails'
  gem 'capybara'
  gem 'factory_girl_rails'
  gem 'launchy'
  gem 'database_cleaner'
end
```

Install gems and generate rspec files:
```bash
bundle
rails g rspec:install
```

Create directory and folder for factory girl:
```bash
mkdir spec/support
touch spec/support/factory_girl.rb
```

Add Rspec configuration to factory_girl.rb:
```ruby
RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
  config.before(:suite) do
    begin
      DatabaseCleaner.start
      FactoryGirl.lint
    ensure
      DatabaseCleaner.clean
    end
  end
end
```

Uncomment this line from rails_helper.rb
```ruby
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
```
