What is bug life cycle?
Bug life cycle also known as defect life cycle is a process in which defect goes through different stages in its entire life. This lifecycle starts as soon as a bug is reported by the tester and ends when a tester ensures that the issue is fixed and won’t occur again.
Why it is called white box testing?
White Box Testing is software testing technique in which internal structure, design and coding of software are tested to verify flow of input-output and to improve design, usability and security. … The term “WhiteBox” was used because of the see-through box concept.
