It scans your source code to build a dependency graph, then lets you write rules declaratively (e.g., \"module B should never be imported by module A\") and assert those rules hold. It's inspired by ArchUnit and integrates naturally with pytest.\n\nThe package depends only on networkx for graph operations and optionally matplotlib for visualization. It supports Python 3.9 through 3.13 and has been actively maintained since its initial release in 2022, with a recent update in August 2025.","worth_installing":"Yes. PyTestArch is actively maintained, has no known vulnerabilities, installs with minimal friction, and solves a real problem\u2014catching architectural violations early. It's well-suited for teams that want to enforce module-level design constraints. The permissive Apache-2.0 license poses no barrier. Start with the basic rule DSL shown in the docs; optional visualization requires matplotlib."},"id":"pytestarch","links":{"html":"https://skillfed.io/packages/pytestarch","md":"https://skillfed.io/packages/pytestarch.md","pypi":"https://pypi.org/project/pytestarch/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-08-08","license_spdx":null,"license_treatment":"permissive","name":"PyTestArch","python_support":"supports_current","summary":"Test framework for software architecture based on imports between modules"},"popularity":{"monthly_downloads":219634,"position":9323,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"4.0.1"}
