How to add Mac-specific gems to bundle on Mac but not on Linux?

Question

I\'m developing a Rails app on a Mac, and I\'m new to testing, so I just added these gems to my Gemfile:

group :test, :development do
  gem          


        

Answer 1

Gemfile actually is a regular ruby file, so you can use something like

case RUBY_PLATFORM
when /darwin/
  gem 'foo'
when /win32/
  gem 'bar'
end
