Answer

It is led by the author of the document to be inspected

Answer

It can only be used for reviewing design and code

Answer

It is led by the author, uses checklists, and collects data for improvement

Question 21

Why does the boundary value analysis provide good test cases?

Accepted Answer

Because errors are frequently made during programming of the different cases near the 'edges' of the range of values

Answer

Because it is an industry standard

Answer

Because only equivalence classes that are equal from a functional point of view are considered in the test cases

Answer

Because the test object is tested under maximal load up to its performance limits

Because verification and validation are not enough to get to know the quality of the software

Answer

Because testing finds more defects than reviews and inspections.

With automated testing you can make statements with more confidence about the quality of a product than with manual testing

Answer

A goal of testing is to show that the software is defect free.
