Defect Life Cycle is the process that a software defect goes through from its discovery to its resolution. It is a series of stages that a defect or bug goes through, starting from the moment it is identified until it is fixed and retested. It is essential for any software development process as it helps to manage and track the progress of the defects that are detected during the testing process.
Defect Life Cycle – Workflow:
Here is a detailed explanation of the Defect Life Cycle and its different stages:
- New: The first stage in the Defect Life Cycle is the New stage. This is when a defect is initially discovered and reported by the tester. The defect is then assigned to a developer for further investigation.
- Assigned: Once the defect is assigned to a developer, they will begin to analyze the issue and start working on a fix. This is known as the Assigned stage.
- Open/Active: When the developer starts working on the defect, it enters the Open or Active stage. During this stage, the developer will fix the issue and update the status of the defect in the defect tracking tool.
- Fixed: Once the developer has fixed the defect, it moves to the Fixed stage. The developer will then pass it back to the tester to be retested.
- Verified: When the tester receives the defect, they will retest it to ensure that the issue has been resolved. If the defect has been fixed, it moves to the Verified stage. If not, it will be reopened and sent back to the developer for further investigation.
- Closed: When the tester has retested the defect and confirmed that it has been fixed, the defect is closed. It is no longer an issue in the software.
- Reopened: If the tester finds that the defect still exists even after it has been fixed and closed, it is reopened and sent back to the developer for further investigation.
- Deferred: A defect can also be deferred if the team decides that it is not critical and can be addressed in a later release or update.
- Rejected: A defect can also be rejected if it is found to be invalid or not reproducible.
Conclusion:
The Defect Life Cycle is an essential part of any software development process. It helps to manage and track defects from their discovery to their resolution. By following a well-defined Defect Life Cycle, software development teams can ensure that all defects are identified, analyzed, and fixed in a systematic and efficient manner. A robust Defect Life Cycle ensures that the software product is of high quality and meets the requirements of its stakeholders.
