Mocking external services in pytest requires isolating dependencies to test public APIs safely. Best practices involve using dedicated mocking techniques to simulate external interactions, ensuring your test suite validates code logic without relying on live services.

Running pytest tests in different modes uses specific commands like `uv run pytest -n logical --color=no` to execute the entire test suite. This allows you to validate test coverage and logic across various environments within your project directory.

Yes, you need the pytest framework and associated plugins to execute test logic and validate test coverage. This Skill focuses on authoring and organizing test code that adheres to project standards, which requires the pytest framework to run.

Improving branch coverage in pytest involves following specific recommendations on the ratio of test to source code. This ensures comprehensive validation of test logic and execution across different branches of your codebase.

Best practices for writing parametrized tests and fixtures in pytest include following structured guidelines on test functions to ensure maintainability. This approach aligns test development with your project's conventions for efficient code organization.
