Regression testing overview

Regression testing compares a new audit against a stored baseline. Each finding is new, known, regressed, or resolved.

Baseline is not approval

A finding in the baseline is not marked acceptable or compliant. It is only a comparison reference. Use classifications for disposition.

Typical loop: audit and review → create or update a baseline → change the app → audit again → triage new/regressed findings → optionally fail CI with policies.

• Baselines — storage, fingerprints, comparison
• Classifications — lifecycle and dispositions
• Updating a baseline — when to refresh the file
• Policies — CI gates
• CI workflow — pipeline practices
