There are two basic

**approaches**one could take in designing test cases: black-box

**approach**and white-box**approach**[15]. In black- box**approach**, the testcases are derived from the external specifications and requirements of the

system.

It is to be expected that systems developed using prototyping

better user interfaces because of user feedback. Also they are likely to be less

ambitious and simple in nature than those developed according to the waterfall

model.
