Agile teams ship fast. Two-week sprints, daily standups, and continuous deployment pipelines have made speed the default. But speed without verification is just organized chaos. When a developer marks a bug as “fixed” and the ticket moves to QA, what happens next determines whether that fix actually reaches production — or quietly breaks something else.
Retesting is often treated as a checkbox. It shouldn’t be. In modern agile environments, retesting is a discipline that, when done well, catches regressions before users do, builds confidence in your release pipeline, and keeps velocity sustainable rather than suicidal.
