Nilify

A gem for null object pattern easy implementation on Ruby objects.

Getting started

Nilify works with Ruby 1.9.3 onwards. Install this gem with:

gem install 'nilify'

Example

Let's check an example for the next Item class.

class Item
    attr_accessor :sku, :title
end

To create a class with mock methods there are two options:

# Option 1
# on the nil class specify the methods to mock
class NilItem
  extend Nilify
  nilify [:sku, :title]
end

# Option 2
# Pass the Item class to mock all the defined methods inside that class.
class NilItem
  extend Nilify
  nilify_from Item
end

Then you can use the mocked methods like this:

> item = Item.new
> item.id
=> nil
> item = NilItem.new
> item.id
=> "id is a mock method"
