Names for this factory, including aliases.

Example:

factory :user, aliases: [:author] do
  # ...
end

FactoryBot.create(:author).class
# => User

Because an attribute defined without a value or block will build an association with the same name, this allows associations to be defined without factories, such as:

factory :user, aliases: [:author] do
  # ...
end

factory :post do
  author
end

FactoryBot.create(:post).author.class
# => User
