2. What is Bug Tracking Maintain a list of bugs in software
Also maintain a list of features and tasks to be done
Assign responsibility for each bug, feature & task
Organize the work to be done
Break up the work into “releases” or other deadlines

What you saw instead

4. Bug Life Cycle

5. A Bug’s Life 1) New: When QA files new bug.
2) Deferred: If the bug is not related to current build or can not be fixed in this release or bug is not important to fix immediately then the project manager can set the bug status as deferred.
3) Assigned: ‘Assigned to’ field is set by project lead or manager and assigns bug to developer.

6. A Bug’s Life
4) Resolved/Fixed: Necessary code changes done, verified, bug status set as ‘Fixed’ and the bug is passed to testing team.
5) Could not reproduce: Developer is not able to reproduce the bug, markes as CNR. QA needs action to check if bug is reproduced and can assign to developer with detailed reproducing steps.
6) Need more information: If bug reproduce steps are not clear, mark it as “Need more information’. QA then needs to provide clearer description of steps.

7. A Bug’s Life
7) Reopen: If QA is not satisfy with the fix and if bug is still reproducible even after fix then QA can mark it as ‘Reopen’ so that developer can take appropriate action.
8 ) Closed: If bug is verified by the QA team and if the fix is ok and problem is solved then QA can mark bug as ‘Closed’.
9) Rejected/Invalid: Some times developer or team lead can mark the bug as Rejected or invalid if the system is working according to specifications and bug is just due to some misinterpretation.

8. What’s it good for? Works great for large teams – communication!
For small teams, good organizational tool even if everybody knows what is going on anyway
Great for planning releases and other deadlines
Also is good documentation for work being done – creates an automatic “paper trail”
