fake2db vs factory_boy
Python test data tools compared
fake2db generates populated databases for development, testing, and demonstrations. factory_boy creates Python objects through reusable factories, focusing on test setup rather than filling standalone databases.
fake2db: Generate Test Databases with Fake Data
fake2db generates databases populated with realistic-looking data for development and testing. It supports several SQL and NoSQL backends, with options for row counts, locales, repeatable seeds, and custom fields.
factory_boy: Create Python Test Data with Factories
factory_boy replaces static test fixtures with configurable factories that build Python objects for individual tests. It supports multiple creation strategies and integrations with popular ORMs, making it useful for projects that need flexible, repeatable test data.

Key differences
- fake2db generates records in six SQL and NoSQL database systems, while factory_boy builds Python objects and ORM instances.
- fake2db is a command-line tool with options for row counts, locales, seeds, and custom fields; factory_boy uses declarative factories with per-call overrides and related-object composition.
- fake2db supports SQLite, MySQL, PostgreSQL, MongoDB, Redis, and CouchDB; factory_boy provides ORM integrations for Django, Mogo, MongoEngine, and SQLAlchemy.
- fake2db is licensed under GPL-2.0, while factory_boy is licensed under MIT.
- fake2db was last pushed on 2019-11-25, so its compatibility with current environments should be checked; factory_boy documents support for active Python versions and PyPy3.
- fake2db can help populate local databases or prepare database-wide test datasets; factory_boy suits Python tests that need tailored objects, related object graphs, or ORM-aware setup.
Choose fake2db if you…
- need to populate a supported SQL or NoSQL database with sample records.
- want command-line options for row counts, locales, seeds, or custom fields.
- are preparing database demonstrations or integration-test datasets without real customer information.
Choose factory_boy if you…
- need reusable Python factories to build objects tailored to individual tests.
- want to create related objects, batches, or saved ORM instances through supported integrations.
- need test data generation within a Python project and can control random seeds when reproducibility matters.
