Question 1
Marks : +2 | -2
Pass Ratio : 100%
What are legacy systems?
new systems
old systems
under-developed systems
none of the mentioned
Explanation:
Legacy systems are the existing systems which may require some modification or maintenance.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
Which regression test selection technique exposes faults caused by modifications?
Efficiency
Precision
Generality
Inclusiveness
Explanation:
Inclusiveness measures the extent to which a technique chooses test cases that will cause the modified program to produce different output than the original program, and thereby expose faults caused by modifications.

two
three
four
five
Explanation:
The stages include: analysis of existing system, characterize proposed modifications, redesign and implement current version.

Question 8
Marks : +2 | -2
Pass Ratio : 100%
Regression testing is a very expensive activity.
True
False
Explanation:
As regression testing is performed many times over the life of the software product, it becomes a costly affair.
