factory_boy: testing like a pro with Camila Maia - DjangoCon US 2022

Django Python Testing

Discover how to test like a pro with factory_boy and Camila Maia at DjangoCon US 2022. Learn best practices for creating complex objects, controlling creation, and ensuring maintainable tests.

Key takeaways

Use factories not to create complex objects, but to allow explicit control over the creation
Avoid using create in factories, as it hits the database, use build instead
Have separate factories for each model, relationships and sub-factories
Factory should contain only the required data to avoid errors and duplication
Avoid duplicating code and use sub-factories to create complex objects
Use fixures only when necessary, avoiding inflation of the fixture
Separate the fixture from the factory to easier maintainability
Use Faker in the factory to create fake data
Pass in the required data to the create method to avoid implicit errors
Fix errors by explicitly defining tests
Use the related_factory to create related objects
Reflect database relationships in the factory
In tests, use assert. For example, assert object.email == '[email protected]'.
