What is SDLC and STLC?

SDLC defines all the standard phases which are involved during the software development process, whereas the STLC process defines various activities to improve the quality of the product. SDLC is a Development Life Cycle whereas STLC is a Testing Life Cycle.

What is bug life cycle with example?

A Defect life cycle, also known as a Bug life cycle, is a cycle of a defect from which it goes through covering the different states in its entire life. This starts as soon as any new defect is found by a tester and comes to an end when a tester closes that defect assuring that it won’t get reproduced again.
