Hi All,
Can any one explain the concept of defect cascading?
Let me explain you with small example. Consider, you are usually collecting mobile number from the user during registerationa and whenever customer logs in, password will be sent to the registered mobile number. In this case, during testing - imagine what will happen if the tester missed to find out that the users are able to register without giving mobile number. This defect of not asking for mobile number, will lead to other defects like (Log in failed due to NO mobile number, etc). This is known as Defect Cascading.
A defect is missed or not noticed during one phase (Here Mobile number is mssing). Due to this defect, you may get sequence of defects at later phases.
