factory-bot-data

Overview

FactoryBot (formerly factory_girl) is the canonical Ruby fixture- factory library - it builds object graphs with referential integrity that raw faker-data cannot (factory_bot-readme).

The split:

• Faker generates field values (Faker::Name.name).
• FactoryBot orchestrates object creation (create(:user, :admin, posts_count: 3)) - including sequence-based unique IDs, associations between models, and trait composition.
