MONGOID

Paul Elliott's Fabrication gem is a slick object generation library. It support's Mongoid out of the box and provides a nice syntax for creating objects with ease for testing.

Fabricator(:person) do
  title "Grand Poobah"
  addresses(:count => 2) do |address, i|
    Fabricate(:address, :streeet => "#{i} Bond St.")
  end
end

Evan Sagge's mongoid-rspec provides RSpec matchers for Mongoid. Includes matchers for associations, options, validations, and fields.

describe Person do
  it { should reference_one :account }
  it { should reference_many :posts }
  it { should be_referenced_in :organization }

  it { should validate_presence_of(:name) }

  it { should have_field(:age).of_type(Integer) }
end

describe Address do
  it { should be_embedded_in(:person).as_inverse_of(:addresses) }
end

Brian Cardarella's remarkable-mongoid gem provides a nice addition of RSpec matchers for Mongoid. It contains the matchers shown below, plus all validation matchers from Remarkable::ActiveModel.

  it { should be_referenced_in :organization }

The Riot-Mongoid gem provides a nice addition of riot assertions for Mongoid. It contains assertions for fields, keys, associations, and validations.

context "Person Model" do
  setup { Person.new }

  asserts_topic.has_field :title,       :type => String

  asserts_topic.has_association :references_one, :account
  asserts_topic.has_association :embeds_many, :addresses

  asserts_topic.has_validation :validates_presence_of, :title
end
