Not create Test directory Not use Test:Unit

Package

Edit GemFile

gourp :development, :test do
   gem 'rspec-rails', '~> 3.1.0'
   #gem 'spring-commands-rspec', '~> 1.0.1'
   gem 'capybara', '~> 2.4.3'
   gem 'factory_girl_rails', '~> 4.4.1'
   gem 'database_cleaner', '~> 1.3.0'
end

Any version is fine.
Please refer rspec | RubyGems.org etc… to check version

Next, you need to update

Maybe, only bundle is fine
