Sell me this defect …

A defect[bug] is an important role in the software development lifecycle, finding a bug[defect] seemed to be easy, but close those defects are not a simple. In our software industries, 25% of bugs are opened more than 12 months, due to various reason, the bug does not explain properly, not communicated properly or prioritized or reports share to right audiences.

Defect[ bug ] Life Cycle.


Open > Defect has been open by anyone from our team, would be a developer, tester, Manager, product owner, and business analyst or end users.

Assigned > Defects should be assigned to the development team or Business Owner Ex: Our testing scope added multiple interfaces then it’s a challenge to get root cause on time, So set up the defect-triage meeting assign those defects to the respective team by Test lead, Scrum Master, Product/business owner or Development Manager. Some scenario defect assigned to Product owner or BA if you need clarifications.

Fixed > We(QA) get the fix from the development team.

Retest > Fixed defect should be deployed to test environment [QA, UAT, Preprod, PRODUCTION ], defect state should be moved to retest state which means tester should ready to start the testing and the fix was deployed on the test environment. Mostly done by development lead/release manager or deployment team.

Rejected > Defect can be rejected due to various reasons, such as invalid defect, assigned to the different team, Data error, Duplicate defect. Those defect should be rejected by Test lead, Scrum Master, Product owner or Development Lead/Manager.

Reopened> > We[qa] team has to retest the defect on time, if it is failed the defect should be reopened or reraised. Mostly done by tester/Test lead/Automation Tester. if unable to retest the defect as a testing team provide the justification.

Deferred > Defect can be moved to the deferred state, due to various reason might be feature ticket, other dependencies and out of scope.

For defect report should be mapped to root cause and it’s mandatory, this helps to reduce defect and improve the quality and prevention.

Security bug > Security bug is more critical one
Ex: Authentication, Security misconfiguration, sensitive data exposure, Unvalidated redirects, cross-site script etc.

Tester error > On Test execution phases, few defects are created, however, those defect(s) are not valid bugs, such as test data setup issue, test cases understanding challenges, execution error.

Usability issue > Application is hard to use by users, pagination, and user forms are added additionally, an additional pop-up message for user error information, error handling issue and more.

Clarifications > For understanding purpose tester can create a defect, this may moved to feature defects or Internal Audit purpose.

UTR[Unable to Reproducible] > During Test execution, few defects are unable to reproducible every time.such as network related issue, content download issue, App crashed etc..
