BlankGem

A blank/empty Ruby gem that does nothing. Useful for testing that only specific Bundler groups are loaded when using a dummy group.

Add this line to your application's Gemfile, ideally under a group you'll never want:

gem 'blank_gem', group: :never

And then execute:

$ bundle install

Simply set Bundler's without option to exclude the group you've put the blank_gem within. For example:

$ bundle config set without 'never'
