Tools and patterns for test maintenance
While Clean Architecture’s boundaries help us write focused tests, maintaining a comprehensive test suite presents its own challenges. As our task management system grows, so do our tests. New business rules require additional test cases, infrastructure changes need updated verification, and simple modifications can affect multiple test files. Without careful organization, we risk spending more time managing tests than improving our system.
When a test fails, we need to quickly understand what architectural boundary was violated. When business rules change, we should be able to update tests systematically rather than have to hunt through multiple files. When adding new test cases, we want to leverage existing test infrastructure rather than have to duplicate setup code.
Python’s testing ecosystem, particularly pytest
, provides powerful tools that align naturally with Clean Architecture’s goals. We’ll explore...
