software-architecture

To enforce software architecture standards during Python refactoring, apply rules for module boundaries, dependency injection, and configuration management. This ensures service boundaries remain clear and codebases stay maintainable throughout structural changes.

Principled Python architecture requires a src-layout project structure. This layout separates source code from tests and configuration, ensuring clean module boundaries, testable imports, and production-ready project organization.

Set up dependency injection by using injectable dependencies and manage configuration via dedicated settings. This approach replaces hardcoded values, ensures modules remain testable, and enforces clear separation between business logic and infrastructure.

Yes, this architectural standard requires mirrored test structures with pytest coverage thresholds and structured logging. It also mandates custom exceptions for error handling to ensure production-ready observability and reliability.

You need ADR documentation when enforcing software architecture standards across Python projects. Architecture Decision Records capture design choices for module boundaries and service structures, reducing design debt during new service builds and messy refactors.

The best way to reorganize mixed Python services is enforcing clear module boundaries and composition over inheritance. Extract logic into testable modules, apply dependency injection, and document API docstrings to reduce design debt.
