Step-by-Step Solution
Solution:
Step 1: Understand sanity testing scope
Sanity testing focuses on verifying specific fixes or features, not the entire application.Step 2: Analyze failure of unrelated features

Unrelated failures after sanity test? Need regression [OK]
Quick Trick: Sanity test checks fixes only; unrelated fails need regression [OK]
