Rosie is a JavaScript library for defining factories that build test data objects, inspired by factory_bot (factory_girl). Factories support attributes, sequences, options, callbacks, and inheritance, making it easy to generate consistent test fixtures.

Use cases

• generate test fixtures for unit tests
• build JavaScript objects with default attributes for testing
• create factory-based test data like factory_bot in JavaScript
• seed databases with realistic test objects
• define reusable object blueprints with sequences and overrides

When to choose

• you need lightweight test data factories in JavaScript or Node.js
• you want factory_bot-style fixtures without a heavy framework
• your tests need repeatable objects with sequences and defaults

When to avoid

• you need fake data generation like names or addresses (use faker instead)
• you are testing in another language with native factory libraries
• you need snapshot or mock-server tooling rather than object factories
