Overview

Regression strategy defines what to re-test when core functionality changes. Rather than re-running everything or hoping nothing broke, QA selects the affected areas by the type of change, authentication, database, API, or UI, and tests the related flows for every affected role and platform.

Why This Exists

Many production incidents are regressions: something that worked yesterday breaks because of an unrelated change. Scoping regression by impact catches those breakages without the cost of re-testing the entire system on every change.
