mongoid-fixture_kit
This package is a Ruby gem that provides a way to load sample data into a MongoDB database for testing purposes. It provides a simple and convenient way to manage test data by defining fixtures in YAML files, which can be loaded into the database before running tests.
This library aims to provide fixtures for Mongoid the same way you have them with ActiveRecord.
Getting Started
Installing
gem 'mongoid-fixture_kit'
Usage
In your tests, add:
class ActiveSupport::TestCase
include Mongoid::FixtureKit::TestHelper
self.fixture_path = "#{Rails.root}/test/fixtures"
end
This is also done by ActiveRecord
, but magically in the railties.
Then when you want to access a fixture:
class UsersControllerTest < ActionController::TestCase
setup do
@user = users(:user_1)
end
test 'should show user' do
get :show, id: @user
assert_response :success
end
end
Features
- Creation of a document from a YAML file.
- ERB inside YAML files
-
belongs_to
relations - Polymorphic
belongs_to
-
has_many
relations -
has_and_belongs_to_many
relations -
TestHelper
module to include in your tests
Notes
Documents are stored with a special attribute __fixture_name
which is used to retrieve it and establish relations.
Mongoid::Document
has a attr_accessor
defined for __fixture_name
, so it doesn't pose any problem if you try to dup
a document for example.
Changes compared to ActiveRecord
- There is an option to load fixtures only once.
- Fixture accessor methods are defined publicly.
These changes are here to let you create another class holding persistent data inside your tests.
class TestData
include Mongoid::FixtureKit::TestHelper
self.fixture_path = "#{Rails.root}/test/fixtures_universes"
self.load_fixtures_once = true
def TestData.instance
@instance ||= ->(){
instance = new
instance.setup_fixtures
instance
}.call
end
private_class_method :new
end
class ActiveSupport::TestCase
include Mongoid::FixtureKit::TestHelper
self.fixture_path = "#{Rails.root}/test/fixtures"
def data
TestData.instance
end
end
# somewhere else
test 'should validate complex data structure' do
assert_nothing_raised do
DataStructure.process(data.structures(:complex))
end
end
