What is the difference between defect prevention and prediction?
defect prevention includes those strategies through which we avoid to occur a defect. for example formal risk analysis, prototyping. in defect prediction those areas are highlighted where there is possibility that defect can occur.
What do you understand by severity and priority of a defect?
Severity and Priority are the attributes of a defect. If we talk about 'Severity of a defect' then it describes how the defect is impacting the functionality of software product whereas 'Priority of a defect' indicates the importance of the defect and when it should be addressed or fixed.In the software project, the severity of a defect should be defined by QA whereas the priority should be defined by Product Owner.Severity of the defect can be categorized into four levels: blocker, critical, major & minor. Similarly, Priority of the defect can be high, medium & low.An organization that provides software testing services needs to ensure that while opening defects, each defect should be assigned with right severity. Incorrect severity and priority mapping will impact overall STLC process and the whole product.
What is the defect notification period?
It is same as DLP ie Defect liability period, which is generally 12 months from the completion period of any project.
What is the difference between profiling and debugging?
Profiling is about executing a program and finding out how much time it spends in each routine. The goal of profiling is often finding slow routines in a program and optimizing them. Profiling is done on working code. Debugging is about finding code that is not working, i.e. has some kind of defect. The program is known to have a defect because some set of inputs causes a set of outputs that are known to be wrong. Debugging is the process of finding the source of the defect in the code and fixing that location and any other downstream locations so that the set of inputs is correctly rendered into the set of outputs.
Does defect mean the same thing as defective?
No, to defect is to move your allegiance to the opposite side in a struggle or war. Defective means something does not work as it should.
