FactoryBot::NamespacedFactories

Affordances for applying Domain Driven design while using FactoryBot

Installation

Add this line to your application's Gemfile:

gem 'factory_bot-namespaced_factories'

And then execute:

$ bundle install

Usage

See:

• thoughtbot/factory_bot#199
• https://github.com/thoughtbot/factory_bot/commit/652818bd1701db67ea03cd062c8259cd7fb37807

There are two main use-cases for Namespaced Factories:

1. Sharing Factories from an Engine or Gem
2. Decomposing an application using domain driven design

Example User Factory

# spec/factories/categories.rb
FactoryBot.define do
  factory :category do
    name { "Classics" }
  end
end

# movies/spec/factories/categories.rb
FactoryBot.define do
  with_namespace(:Movies) do
    factory :category do
      name { "Emmy Winners" }
    end
  end
end

# movies/spec/category_spec.rb
category = FactoryBot.build(:category)
expect(category).to be_kind_of(Movies::Category)

# spec/category_spec.rb
category = FactoryBot.build(:category)
expect(category).to be_kind_of(Category)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
