(ii) Sanity testing
(iii) Breadth test and depth test
(iv) Confirmation testing

The largest percentage of total life cycle cost of software is

a) Design cost
b) Coding cost
c) Maintenance cost
d) Testing cost

Software reengineering is concerned with

(i) Improving the software design and structure without changing functionality
(ii) Adding new features to the software
(iii) Building a new system from scratch
(iv) Fixing bugs in the system

Regression testing is performed to:

(i) Test a new module
(ii) Ensure recent changes didn't affect existing functionality
(iii) Improve system performance
(iv) Identify hardware errors
