What is Bug life Cycle Software Testing

The bug life cycle, also known as the defect life cycle, represents the various stages a software defect goes through from the time it is identified until it is fixed and verified. The bug life cycle provides a systematic approach to managing and tracking defects in a software development and testing process. The typical bug life cycle includes the following stages:

New:

Description: This is the initial stage where a tester or a team member reports a potential defect or bug. It could be based on the results of testing, customer feedback, or any other source.
Status: The status of the bug is set to “New.”
Open:

Description: After the bug is reported, it is reviewed by a team lead or a manager who assigns it to the development team for further investigation.
Status: The status changes to “Open.”
Assigned:

Description: The bug is assigned to a developer who will be responsible for investigating, fixing, and resolving the issue.
Status: The status changes to “Assigned.”
In Progress:

Description: The developer starts working on fixing the bug, making the necessary code changes to address the reported issue.
Status: The status changes to “In Progress.”
Fixed:

Description: The developer has made the necessary code changes to address the reported issue, and the bug is considered fixed.
Status: The status changes to “Fixed.”
Ready for Retest:

Description: After the bug is fixed, it is assigned back to the testing team for retesting to ensure that the reported issue has been successfully resolved.
Status: The status changes to “Ready for Retest.”
Reopened:

Description: If the testing team finds that the bug still exists or if new issues are identified during retesting, the bug is reopened.
Status: The status changes to “Reopened,” and the bug goes back to the development team for further investigation and fixing.
Verified:

Description: Once the testing team verifies that the bug has been successfully fixed and that the software now meets the expected behavior, the bug is marked as “Verified.”
Status: The status changes to “Verified.”
Closed:

Description: The bug is closed when it has been fixed, retested, and verified successfully. A formal closure report may be generated, summarizing the bug-fixing process.
Status: The status changes to “Closed.”
Deferred:

Description: Sometimes, a decision is made to defer fixing a bug to a future release. In such cases, the bug is marked as “Deferred.”
Status: The status changes to “Deferred.”

The bug life cycle helps teams manage defects efficiently, ensuring that each bug is properly documented, addressed, and verified before closing. It provides visibility into the status of each defect and facilitates communication between development and testing teams. The bug life cycle may vary slightly from one organization or project to another, but the general stages remain consistent.
