One of the most challenging aspects of writing good tests is maintaining test fixtures. Good test fixtures motivate developers to write better tests, and bad fixtures can cripple a system to a point where developers fear and avoid them all together. The key to maintaining good fixtures is to find a good balance between flexibility and usability. Good fixtures are ones that are easy to use and easy to modify.
In my latest article for RealPython I share some insights on how to maintain good test fixtures for Django models using Pytest. The article covers everything from setting up Pytest for a Django project, creating test fixtures and how to create dependency between fixtures.
The article focuses on a pattern called "factory as a service". Using this pattern, you can create fixture for Django models that depend on other fixtures. This makes it easier to set up data for tests and focus on the the scenario at hand rather than setting up the data.
