Defect life cycle includes stages like New, Assigned, Open, Fixed, Retest, Reopen, and Closed.
STLC focuses on preventing defects, while defect life cycle focuses on managing and resolving defects.
Example: In STLC, test cases are designed and executed to verify the software functionality. In defect life cycle, defects are reported, assigned, fixed, retested, and closed.
Example: A defect is identified during testing, logged in a defect tracking tool, assigned to a developer, fixed by the developer, retested by the tester, and closed if the defect is resolved.
