Ein moderner DevOps Prozess wäre ohne Feature Branches und Pull-Request Workflows nicht mehr denkbar. Wie wird nun diese Änderung verifiziert? Oft schafft nur ein Deployment in eine isolierte PR Umgebung Klarheit. Somit sind Tests im Gesamtkontext mit Umsystemen und echter Datenpersistenz möglich, der Deployment und Upgrade Vorgang kann mitgetestet werden und nicht zuletzt kann auch ein Product Owner die Änderung an einem laufenden System anschauen.
