Can you explain the structure of bug life cycle?

Answer 1

The Bug life cycle consists the following stages
1)New
2)Open
3)Assign
4)Test
5)Reopened or Rejected or Differed
6)Verified
7)Closed

1)New : When the Bug is detected by the tester it is in the new stage.It is not still approved by testing lead.

2)Open:If the testing lead finds the bug as genuine he assigns it to the open stage

3)Assign:The lead then assigns the code containing the bug for debugging to a developer and puts it in the assign stage

4)Test:The software developer may debug the code and send it back to testing .And puts it into Test stage.

5)Differed: The software developer may not fix the bug and instead may be of the opinion of fixing the bug in the next release .In this case he puts it in to differed stage.
Differ may be due to
a)Less time for the release
b)The bug does not have any sizeable effect

6)Rejected :Some times the Developer may feel that there is no bug or the bug that exist
will not have any effect .In this case he puts it into Rejected stage.

7)Reopened:After it is send back by the developer the Tester reopens it and tests it again.
Here the life cycle is repeated.

8)Verified: After the tester is confirmed that the bug is debugged.He assigns it to verified stage.

9)Closed:After verifying all the bugs have been debugged the life-cycle is closed.
