Foundations of Software Testing: Fundamental Algorithms and Techniques

Preliminaries

fault with respect to a fault model in a finished product. Thus, the aim

is to verify the correctness of a finished product. Testability in software

focuses on the verification of design and implementation.

1.7 SOFTWARE AND HARDWARE TESTING

There are several similarities and differences between techniques used

for testing software and hardware. It is obvious that a software applica-

tion does not degrade over time, any fault present in the application will

remain and no new faults will creep in unless the application is changed.

This is not true for hardware, such as a VLSI chip, that might fail over

time due to a fault that did not exist at the time the chip was manufac-

tured and tested.

This difference in the development of faults during ...
