Ensure testing dependencies are properly organized, avoid redundancy, and proactively manage unmaintained packages. Place testing-specific dependencies in the correct dependency groups (e.g., group.test.dependencies rather than group.dev.dependencies). Before adding new testing libraries, verify that existing dependencies don’t already provide the same functionality - for example, use pytest-mock instead of adding a separate mock dependency. Monitor the maintenance status of testing dependencies and plan migration paths for stalled projects.
Example of proper dependency management:
[tool.poetry.group.test.dependencies]
pytest-httpserver = "^1.0.8" # Correctly placed in test group
pytest-mock = ">=3.9" # Use existing mock functionality
# Avoid: mock = "^2.0" # Redundant with pytest-mock
# Plan migration for unmaintained dependencies
urllib3 = "<2.3" # Temporary constraint due to httpretty compatibility
# TODO: Migrate from httpretty to mocket for better maintenance
This approach maintains a clean, maintainable test infrastructure while avoiding dependency conflicts and technical debt.
