The FactoryBot.find_definitions method loads in all factory_bot definitions across the project.

The load order is controlled by the FactoryBot.definition_file_paths attribute. The default load order is:

  1. factories.rb
  2. test/factories.rb
  3. test/factories/**/*.rb
  4. spec/factories.rb
  5. spec/factories/**/*.rb


The .find_definitions method is called automatically by factory_bot_rails after initialize. The .definition_file_paths can be set during initialization (e.g. config/initializers), or via Rails.application.config.factory_bot.definition_file_paths.
