Understanding the Defect/Bug Life Cycle in Software Testing

The defect life cycle is the current state of a bug, and its goal is to precisely convey the current state of an error in order to track better and understand the actual progress.

FREMONT, CA: The defect life cycle is also known as a bug life cycle and  It is a process in which a bug goes through different stages in its entire life. Consider the bug as a lively object that has different states throughout its life right from the state it’s opened by the tester to the state of getting closed after getting fixed. A software bug may show up because of a mistake the software developer made during the product's development. Trying to find all software errors during the development phase is the tester's or quality assurance's (QA) top priority to have them fixed leading up to the software's release.

The Life Cycle of a Bug
-The defect is discovered by the tester.
-The defect has been assigned a new status.
-A defect is reported to the project manager for investigation.
-The project manager determines whether or not a defect is valid.
-The defect is rejected in the case of invalidation.
-The project manager assigns the status rejected. If the defect is not rejected, the next step is to determine whether it is within the scope of the project.
-The manager checks to see if a similar defect has been reported previously. If yes, the defect is given the status duplicate.
-If not, the defect is assigned to a developer, who begins working on the code. The defect is given the status of in progress at this point.
-Once the code has been fixed and the status of the defect is fixed.
-The code will be tested at least by the tester. If the Test Case passes, the defect is resolved. If the test cases fail once more, the defect is reopened and assigned to a developer.

Generally, the bug life cycle consists of the following steps:
 Detection: A bug is reported or identified by the tester.
 -Analysis: The bug is analyzed and assessed by the developer.
 -Reproduction: The bug is reproduced in a controlled environment to confirm its existence.
 -Resolution: The bug is fixed by the developer.
 -Retesting: The fixed bug is tested, to check if it works as intended.
 -Closure: The bug is closed, after verifying that the issue is resolved.

Any company must resolve bugs to deliver defect-free products to the market. Make sure that bugs are detected and resolved efficiently while the production phase is running. To maintain a high level of quality, ensure that the final product delivered to the end user is bug-free.
