Defect age is the time elapsed between the day the tester discovered a defect and the day the developer got it fixed.
While estimating the age of a defect, consider the following points:
- The day of birth of a defect is the day it got assigned and accepted by the development team.
- The issues which got dropped are out of the scope.
- Age can be both in hours or days.
- The end time is the day the defect got verified and closed, not just the day it got fixed by the development team.
