I was being lazy and have just overwritten the internal of Rspec for implementation, so never use this:)
This gem is a RSpec extension to define multiple helpers with let.
Every helpers defined is lazy loaded.
Add this line to your application's Gemfile:
gem 'rspec-nlet'And then execute:
$ bundle
Or install it yourself as:
$ gem install rspec-nlet
# define multiple helpers
> let(:one, :two, :three) { [1,2,3] }
> one # => 1
> two # => 2
> three # => 3
# define a helper
> let(:single) { 'single' }
> single # => 'single'
# accept nil
> let(:nil) { nil }
> nil # => nil
# can be overriden
> let(:over, :ride) { ['over', 'ride'] }
> let(:over, :ride) { [:over, 'riden'] }
> over # => :over
> ride # => 'riden'
# raise an error when too few names are passed
> let(:too, :few) { [1,2,3] }
> few # => StandardError (Too few names)
# raise an error when too many names are passed
> let(:too, :many) { [1] }
> many # => StandardError (Too many names)
# raise an error when names are duplicated
> let(:dup, :dup) { [1,2] }
> dup # => StandardError (Names are duplicated)
# raise an error when a block returns an object other than Array
> let(:no, :array) { 1 }
> no # => StandardError (Block returns non Array object)After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
