From discovery to resolution a defect moves through a definite lifecycle called the defect lifecycle
Lets look into it. Suppose a tester finds a defect .The defect is assigned a status , new.
The defect is assigned to development project manager who will analyze the defect.He will check whether it is a valid defect.
Consider that In the flight reservation application, the only valid password is mercury. But you test the application for some random password , which causes logon failure and report it as defect .Such defects due to due to corrupted test data , miss configurations in the test environment , invalid expected results etc are assigned a status rejected
If not , next the defect is checked whether it is in scope. Suppose you find a problem with the email functionality. But it is not part of the current release .Such defects are postponed
Next, manager checks whether a similar defect was raised eelier . If yes defect is assigned a status duplicate
If no the defect is assigned to developer who starts fixing the code. During this stage defect is assigned a status in- progress.
Once code is fixed. Defect is assigned a status fixed
Next the tester will re-test the code. In case the test case passes the defect is closed.
If the test cases fails again the defect is re-opened and assigned to the developer
Consider a situation where during the 1st release of Flight Reservation a defect was found in Fax order which was fixed and assigned a status closed
During the second upgrade release the same defect again re-surfaced. In such cases, a closed defect will be re-opened. That’s all to Bug Life Cycle
