The mongoid-rspec library provides a collection of RSpec-compatible matchers that help to test Mongoid documents.
Tested against:
- MRI:
2.6.x,2.7.x,3.0.x,3.1.x,3.2.x - Mongoid:
4,5,6,7,8,9
See .github/workflows/rspec.yml for the latest test matrix.
Drop this line into your Gemfile:
group :test do
gem 'mongoid-rspec'
endThis gem is compatible with Mongoid 3, 4, 5, 6, 7, 8, 9.
Add to your rails_helper.rb file
require 'mongoid-rspec'
RSpec.configure do |config|
config.include Mongoid::Matchers, type: :model
endAdd to your spec_helper.rb file.
require 'mongoid-rspec'
RSpec.configure do |config|
config.include Mongoid::Matchers
endclass Post
include Mongoid::Document
end
RSpec.describe Post, type: :model do
it { is_expected.to be_mongoid_document }
endclass User
include Mongoid::Document
include Mongoid::Attributes::Dynamic
end
RSpec.describe User, type: :model do
it { is_expected.to be_dynamic_document }
endWith full timestamps.
class Log
include Mongoid::Document
include Mongoid::Timestamps
end
RSpec.describe Log, type: :model do
it { is_expected.to have_timestamps }
endWith short timestamps.
class User
include Mongoid::Document
include Mongoid::Timestamps::Short
end
RSpec.describe User, type: :model do
it { is_expected.to have_timestamps.shortened }
endWith only creating or updating timestamps.
class Admin
include Mongoid::Document
include Mongoid::Timestamps::Create
include Mongoid::Timestamps::Update
end
RSpec.describe Admin, type: :model do
it { is_expected.to have_timestamps.for(:creating) }
it { is_expected.to have_timestamps.for(:updating) }
endWith short creating or updating timestamps.
class Post
include Mongoid::Document
include Mongoid::Timestamps::Create::Short
end
RSpec.describe Short, type: :model do
it { is_expected.to have_timestamps.for(:creating).shortened }
endclass Post
include Mongoid::Document
store_in database: 'db1', collection: 'messages', client: 'secondary'
end
RSpec.describe Post, type: :model do
it { is_expected.to be_stored_in(database: 'db1', collection: 'messages', client: 'secondary') }
endIt checks only those options, that you specify. For instance, test in example below will pass, even though expectation contains only database option.
class Comment
include Mongoid::Document
store_in database: 'db2', collection: 'messages'
end
RSpec.describe Comment, type: :model do
it { is_expected.to be_stored_in(database: 'db2') }
endIt works fine with lambdas and procs.

include Mongoid::Document
store_in database: ->{ Thread.current[:database] }
end
