Purpose

Proper pytest configuration ensures fast test discovery, correct isolation, and consistent behavior across environments. This skill provides production-ready configuration patterns.

Do NOT use for writing tests themselves (use layer-specific testing skills), debugging failures (use test-debug-failures), or mocking strategies (use pytest-mocking-strategy).

Quick Start
