Functional Testing<br />
• The problem with functional testing is completeness – “Has<br />
sufficient testing been done?”<br />
• It is impossible to exhaustively test all behaviors and<br />
parameters.<br />
• There is always a possibility that some untried combination<br />
of parameters and sequences would reveal a new behavior<br />
that is unacceptable.<br />
• A two tiered approach is used here, where exhaustive tests<br />
are to be carried out in the functional block level by the sub<br />
block designers, but even this is not exhaustive.<br />
