FactoryBot::Refinements

Extensions for factory_bot

Installation

Add this line to your application's Gemfile:

gem 'factory_bot-refinements'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install factory_bot-refinements

Usage

Add the following code to your test file:

# ActiveRecord extensions
using FactoryBot::Refinements::ActiveRecord

# RSpec extensions
using FactoryBot::Refinements::RSpec

# Or both of them
using FactoryBot::Refinements

FactoryBot::Refinements::ActiveRecord

Add a set of methods to create/build a record using a factory for has_many associations. All arguments, including keyword arguments and a block, will be delegated to the factory.

By default, the factory to use will be automatically looked up from the association's class. You can also specify an arbitrary one with factory().

using FactoryBot::Refinements::ActiveRecord

describe MyApp do
  example do
    user = create(:user)

    user.posts.create_with_factory(:published, title: 'hello')
    # Equivalent to:
    # FactoryBot.create(:post, :published, user: user, title: 'hello')

    user.posts.factory(:published_post).create_with_factory
    # Equivalent to:
    # FactoryBot.create(:published_post, user: user)

    user.posts.build_with_factory
    # Equivalent to:
    # FactoryBot.build(:post, user: user)
  end
end

FactoryBot::Refinements::RSpec

Add a set of short-hand methods to the describe/context block that do FactoryBot.create/build and let/let! together. All arguments except the first, including keyword arguments and a block, will be delegated to the factory as-is.

using FactoryBot::Refinements::RSpec

describe MyApp do
  create :user, name: 'alice'
  # Equivalent to:
  # let!(:user) { FactoryBot.create(:user, name: 'alice') }

  create :user.as(:bob), :admin, name: 'bob'
  # Equivalent to:
  # let!(:bob) { FactoryBot.create(:user, :admin, name: 'bob') }

  create_lazy :user
  # Equivalent to (let, not let!):
  # let(:user) { FactoryBot.create(:user) }

  build :user
  # Equivalent to:
  # let!(:user) { FactoryBot.build(:user) }

  build_lazy :user
  # Equivalent to:
  # let(:user) { FactoryBot.build(:user) }
end

Limitations

Due to scope constraints, these factories do not have access to other let values. Therefore, it is recommended to use them for fixture-like fixed data setups. If you need let to build associations, consider using RSpec::LetAs.
