Structure unit and integration tests under a unified tests/ tree using pytest, separating them via explicit markers. This layout enables a single-command workflow to execute the full test suite from the project root.

Manage reusable setup in pytest using fixtures and conftest files with proper scoping. This approach keeps tests fast and isolated by ensuring setup logic executes only when necessary across test modules.

Mocking at boundaries isolates external dependencies without over-mocking internal logic by using autospec. This ensures mocks match the actual interface signatures, preventing drift and maintaining test reliability.

Yes, you can run both unit and integration tests with a single pytest command from the project root. The Skill enforces a unified workflow with explicit markers to separate test types while executing the full suite together.

Parametrize Python tests using the pytest parametrize decorator to systematically cover input variations and edge cases. This generates distinct test cases from a single test function, ensuring broad coverage without code duplication.

Use descriptive naming conventions for pytest test modules and functions so test names read as sentences. This clarifies test intent, simplifies debugging, and enforces concise test modules across the project.
