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.
