7.2.1. Typical Bug Status Flow

The Defect Lifecycle describes the states a bug goes through from discovery to closure.

The Defect Lifecycle is a structured process that a bug follows from the time it is identified until it is resolved and closed. Understanding this flow is essential for managing defects effectively. Each state represents a specific phase in the bug's life, highlighting the actions being taken and the status of the bug at that moment.

Think of the bug status flow like a patient in a hospital. Just like a patient goes through various stages from admission to discharge (i.e., admission, diagnosis, treatment, recovery, and discharge), a bug goes through similar stages from being logged as a defect to being resolved and closed.

1. New → Bug is logged
2. Assigned → Assigned to a developer or team
3. Open → Confirmed and under investigation
4. In Progress → Developer is working on it
5. Fixed → Developer has implemented a fix
6. Retest → QA re-tests the fix
7. Verified → Fix works as expected
8. Closed → Bug is fixed and no longer active

This chunk details the specific stages that a bug goes through in its lifecycle. Each stage plays a crucial role:

1. New: The bug is entered into the tracking system.
2. Assigned: A developer or team is designated to address the bug.
3. Open: The status is confirmed and the investigation begins.
4. In Progress: The developer actively works on fixing the bug.
5. Fixed: A potential solution has been implemented.
6. Retest: Quality Assurance (QA) teams test the fix to ensure it resolves the issue.
7. Verified: QA confirms that the fix works as intended.
8. Closed: The bug is officially marked resolved and no longer active.

Consider a car repair shop. When a car arrives with a problem, it’s logged in the system (New), then assigned to a mechanic (Assigned), who confirms the issue (Open) and begins work (In Progress). After fixing the car (Fixed), the mechanic may ask a tester to drive it (Retest), confirming it runs well (Verified), before finally completing the service (Closed).

● Rejected → Bug is invalid or not reproducible ● Deferred → Bug is valid but postponed for future release ● Duplicate → Bug already exists ● Reopened → Bug still persists after fix attempt

In addition to the typical states, there are also alternate statuses that bugs can encounter:

1. Rejected: Indicates that the reported issue was found to be invalid or could not be reproduced.
2. Deferred: Acknowledges that the bug is real but the fix will be postponed to a future release due to various reasons such as prioritization.
3. Duplicate: Indicates that a report for the same issue already exists.
4. Reopened: Occurs when a bug thought to be fixed still presents problems; thus, it comes back for further investigation.

Think of this as customer service at a retail store. If a product complaint is made and found to be untrue, it may be rejected. If a valid complaint needs addressing but can wait, it's deferred. If a customer comes with the same complaint as another, it’s noted as a duplicate. Finally, if a customer reports a problem again after being told it was fixed, it gets reopened for further examination.

Use bug-tracking tools like JIRA, Bugzilla, or Azure DevOps to manage defect states.

Bug-tracking tools play a vital role in the defect lifecycle. These tools help teams efficiently manage bugs by tracking their status, assigning them to the right team members, documenting progress, and facilitating communication between developers and testers. Tools like JIRA, Bugzilla, and Azure DevOps streamline the process and ensure that no bugs are overlooked.

Think of a bug-tracking tool as a digital project manager. Just as a project manager keeps track of tasks, deadlines, and team members in a project, a bug-tracking tool keeps tabs on bugs, their statuses, and who is responsible for fixing them.
