Different requirements for packages, using, building, and testing

General Usage

Isn’t this what got discussed in: Development, Test, and Production Environments?

with it you can do something like this for REQUIRE:

gem 'httparty'

group :development, :test do
  gem 'better_errors'
end

group :production do
  gem 'postgres'
end

// edit: i just used a gemfile instead of a require file because i had one on hand
