mongoid-fixture_set
This projects aims to provide fixtures for Mongoid the same way you have them with ActiveRecord.
I am relying on the source of ActiveRecord and Mongoid to create this gem.
Please report any issue you may find.
If you'd like to contribute, but pull requests are welcome!
Install
gem 'mongoid-fixture_set'
How to use
In your tests, add:
class ActiveSupport::TestCase
include Mongoid::FixtureSet::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
@resource = users(:geoffroy)
end
test 'should get show' do
get :show, id: @resource
assert_response :success
end
end
Currently working features
- Creation of a document from an YAML file.
-
belongs_to
relations - ERB inside YAML files
- YAML DEFAULTS feature
- Polymorphic
belongs_to
-
has_many
relations -
has_and_belongs_to_many
relations -
TestHelper
module to include in your tests
Notes
Original fixtures from ActiveRecord
also uses a selection based on class_names
for which I haven't seen any use case, so I did not port this feature yet.
I did not find how ActiveRecord::TestFixtures
defines its fixture_table_names
so I'm simply searching for all YAML files under self.fixture_path
, which is enough for what I want.
Array attributes are receiving a special treatment, i.e. they are joined with new values, not replaced by the new one. This is used for has_and_belongs_to_many
relations.
Documents are stored with a special attribute __fixture_name
which is used to retrieve it and establish relations.
Mongoid::Document
has an 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.
This changes are here to let you create another class holding persistent data inside your tests.
class TestData
include Mongoid::FixtureSet::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::FixtureSet::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
