Performance of white box testing

Question

Briefly describe what are the reasons behind to performance of white box testing?

Answer 1

There are three reasons behind the functioning of white box testing which are illustrated below:

a) Programmers might contain some incorrect suppositions while designing or implementing certain functions. Due to this there are chances of containing logical errors in the program. To discover and correct these logical errors procedural details require to be examined.

b) Certain suppositions on flow of control and data might lead programmer to make design errors. To expose the errors on logical path, the white box testing is essential.

c) There might be certain typographical errors which remain undetected even after syntax and type checking methods. These errors can be exposed throughout white box testing.
