Don’t Retest Everything: Auditable Regression Scoping for Safety-Critical Systems
Abstract
In safety-critical software development, changes often span technical and organisational boundaries, e.g., repositories, interfaces, libraries, and teams. Under certification and traceability requirements, these changes create a difficult regression-testing problem: organisations must determine what must be revalidated and provide an auditable justification for those decisions. In practice, the resulting uncertainty often drives overly conservative strategies, where large portions of the system are retested after changes or updates, even when a narrower scope would suffice.
