The original title is "Pytest pt2 - Mastering Pytest Fixtures"

Short summary

A practical guide to pytest fixtures covering scopes (function through session), yield-based setup and teardown, autouse for automatic cleanup, and conftest.py for shared fixtures. Examples use PySpark SparkSession to illustrate scope tradeoffs between isolation and speed. The post is the second in a series on pytest testing fundamentals.

• •Fixtures eliminate test duplication by defining reusable setup once and injecting where needed
• •Scope parameter controls fixture lifetime from per-function to per-session
• •yield separates setup from teardown; autouse=True runs fixtures automatically without explicit requests
