Bug Tracking Life Cycle

What is a bug, a defect and a failure?

1. Bug-> A software bug is an error, flaw in a program that prevents it from behaving as intended. Most bugs arise from mistakes and errors made by people in either a program’s source code or its design, and a few are caused by compilers producing incorrect code.

2. Defect-> Defect is something which is in the requirement document and it is not implemented or it is implemented in a wrong way.

3. Failure-> It is an antithesis of software from its expected delivery or service.

Explanation of bug life cycle:

Bug life cycle is also known as defect life cycle.It varies from organization to organization and also from project to project, as it is governed by the software testing process and also depends upon the tools used.    

Bug status description:

1. New Status: Tester provides “New” status while reporting for the 1st time.

2. Open/Assign Status: After a tester has posted a bug, the lead of the tester validates that the bug is reasonable then they forward to the corresponding person with changing the state to "Opened".

3. Reject Status: Developer rejects if the bug is invalid then the state of the bug is changed to "Rejected".

4. Deferred Status: When the bug is changed to the deferred state, the bug is expected to be fixed in future releases.

5. Duplicate Status: If the bug is already raised then the bug status is changed to "Duplicated".

6. Fixed Status: The bug is fixed and ready for testing.

7. Closed Status: If the bug is verified by the QA and if it’s fixed then the bug status should be “Closed”.

8. Reopen Status: When the bug is not fixed, QA reopens the defect then the state of the bug is “Reopened”
