Definition

Regression testing verifies that migrated pages, forms, and checkout flows still work after template or plugin changes.

Why it matters during migration

Maintain a test checklist per template type: homepage, service, product, blog, contact.

How To WP applies this

Our audits and delivery playbooks reference regression testing when scoping redirects, QA, and launch monitoring — especially for Migration workstreams.
