We are currently on a two week sprint, and at the end of the sprint we have working functionality that we start delivering through a Beta/Staging/Production type environment. When the developer is done with their Jira issue, they set it to "Ready to test" custom status. The testers then see these issues and start testing them. However, the tester may or may not finish the testing task within the sprint. We want to track the Velocity of the developers so we have better insight to estimations etc...
Has anyone been able to successfully integrate testing into a sprint without killing the velocity? I know velocity is a (and should be) a team velocity, not an individual. But if it's not an individual developer, how should we estimate using velocity numbers?
