factory_girl

FactoryBot::DefinitionProxy#method_missing

Calls add_attribute using the missing method name as the name of the
attribute, so that:

  factory :user do
    name 'Billy Idol'
  end

and:

  factory :user do
    add_attribute :name, 'Billy Idol'
  end

are equivalent.

If no argument or block is given, factory_bot will look for a sequence
or association with the same name. This means that:

  factory :user do
    email { create(:email) }
    association :account
  end

and:

  factory :user do
    email
    account
  end

are equivalent.
