transition between Test, Bug, Test
In Scrum: When the Product Owner find, register and set a bug to developer, how can the Product Owner know when the bus is ready for test?
(Jhon is then Product Owner and Peter is a member team)
1. Product BackLog
2. Sprint BackLog
4. Task is Done.
5. Jhon Find a Bug.
6. Jhon Create Bug link with the Task in TFS and Assigned To Peter.
7. Set Bug to Appoved.
8. Set Bug to Committed.
9. Create a new Task link with the Bug.
10. Peter do the new Task.
11. Peter set the new task to Done.
12. Jhon must has a report with Bugs with "State Committed" and link Task with "State Done" ?
How can Jhon know that the new Task is Done and the First Task can Test again?
I know the scrum is about people over tools but the test members must have a artefact to know when a bug is ready to test again and no only daily scrum, email, etc.
Thanks a lot and sorry for my English.
