Explain the prototyping approaches in software process.
Two approaches
i. Evolutionary prototyping - In this approach of system development, the initial prototype is prepared and it is then refined by number of stages to final stage.
ii. Throw-away prototyping - Using this approach a rough practical execution of the system is produced. The requirement problems can be recognized from this implementation. It is then discarded. System is then developed using some dissimilar engineering paradigm.
Software faults are unseen programming errors. Software faults are errors in the correctness of the semantics of computer programs.
Q. Define software testing. Explain various level of testing? Ans: Software testing- It is a process used to help identify the completeness, correctness and quality of develo
