Introduction
This blog will discuss the defect or bug life cycle in software testing. The defect life cycle can differ from company to company and from project to project depending on many factors, including company policy, the type of software development paradigm used (such as Agile or Iterative), project timescales, team structure, etc.
Some organisations, projects, or managers may use a more thorough life cycle, such as the one described below, whereas others may use a smaller life cycle.

What is Defect Life Cycle?
In software testing, the defect or bug life cycle refers to the exact sequence of stages a defect or bug experiences. The defect life cycle aims to make the defect-fixing process systematic and practical by making it simple to coordinate and communicate the current status of the defect, which changes, to various assignees.
Defect Status
Bug status or defect: The stage in the defect life cycle at which the flaw or bug is now called the status. To more accurately track and comprehend the progress of the defect life cycle, the defect status goal is to accurately represent the current condition or progress of a defect or bug.
From project to project, a fault may pass through different states. The lifespan model below shows all potential conditions.
New:
A new fault is first logged and uploaded and considered unique.
Assigned:
After the tester posts a bug, the tester’s lead reviews the bug and assigns it to the development team.
Open:
The developer gets to work on studying and fixing the defect.
Fixed:
A bug can be marked as “Fixed” when a developer makes the required code modification and confirms the change.

Retest in progress:
After the flaw is corrected, the developer provides the tester with a specific code to retest the code. The status is “pending retest” because the software testing is still pending from the testers’ perspective.
Retest:
At this stage, the tester retests the code to see if the developer has fixed the defect and changes the status to “Retest.”
Verified:
The tester retests the bug after the developer fixes it. If no software flaw is found, the fault has been addressed, and the status has been changed to “confirmed.”
Reopen:
The tester updates the status to “reopened” if the bug still exists after the developer has repaired it. The bug goes through its life cycle once more.
Closed:
When a bug is declared to be fixed, the tester marks it as “Closed.”
Duplicate:
The status is changed to “duplicate” if the defect occurs twice or relates to the same notion as the bug.
Rejected:
The defect is changed to “rejected” if the developer believes it is not an actual defect.
Deferred:
If a defect is not a top priority but is anticipated to be fixed in the upcoming release, it is given the “Deferred.”
Not an error:
The status of a problem is “Not a bug” if it does not impact the application’s operation.
Conclusion
So far, we have briefly discussed the bug or defect life cycle in software testing. Some states above may not be present in simpler bug life cycle implementations. When the faults are investigated later, this might not give as much insight into the bug/defect metrics.
The bug’s Life Cycle includes various states for it.
