what steps will be in bug life cycle.
i have seen two types.

simple way to understand bug life cycle …
Bug Tracking involves two main stages: reporting and tracking.
Report Bugs
Once you execute the manual and automated tests in a cycle, you report the bugs (or defects) that you detected. The bugs are stored in a database so that you can manage them and analyze the status of your application.
When you report a bug, you record all the information necessary to reproduce and fix it. You also make sure that the QA and development personnel involved in fixing the bug are notified.

Track and Analyze Bugs
The lifecycle of a bug begins when it is reported and ends when it is fixed, verified, and closed.

  •     First you report New bugs to the database, and provide all necessary information to reproduce, fix, and follow up the bug.
  •     The Quality Assurance manager or Project manager periodically reviews all New bugs and decides which should be fixed. These bugs are given the status Open and are assigned to a member of the development team.
  •     Software developers fix the Open bugs and assign them the status Fixed.
  •     QA personnel test a new build of the application. If a bug does not reoccur, it is Closed. If a bug is detected again, it is reopened.

Communication is an essential part of bug tracking; all members of the development and quality assurance team must be well informed in order to insure that bugs information is up to date and that the most important problems are addressed.
The number of open or fixed bugs is a good indicator of the quality status of your application. You can use data analysis tools such as re-ports and graphs in interpret bug data.

Core phases are NEW—> OPEN—> FIXED—> CLOSED. but Interviewer expects you to explain it in depth:-

Have a serious look at the Below described Bug Life Cycle.

  1. New —>2) Opened ----> 3) Rejected . ( May be Reopened in future )
  2. New —> 2) Opened----> 4) Deferred. ( May be Reopened in future )
  3. New----> 2) Opened----->5) Assigned. ( Fixing Starts )
  4. New–>2)Opened–>5) Assigned–> [ After fixes] 6)Fixed–> [ Retest fails ]–>( 7) Reopened–> 5) Assigned.
  5. New----> 2) Opened----> 5) Assigned-----> 6) Fixed—>[ Retest passes] —> 8) Closed.

Note:- If Problem returns then even the Closed bugs can be Reopened and further Assigned …
