django-test-migrations allows testing Django schema and data migrations. It provides tools to verify migrations' order, names, and data integrity, crucial for ensuring data consistency during complex database changes. This tool is designed to isolate and test migration logic, allowing for proactive identification of potential issues before deployment. It leverages a flexible approach enabling testing both forward and backward migrations with granular control over the database state.
The library offers precise control over migration execution, supporting both forward and backward tests. It includes a robust plan generation feature to validate migration order, crucial for complex projects with dependencies. Integration with pytest and unittest provides seamless testing within existing testing workflows. The library is fully typed, promoting code reliability and maintainability.
