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.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
Which selective retest technique selects every test case that causes a modified program to produce a different output than its original version?
Coverage
Minimization
Safe
Maximization
Explanation:
Safe techniques do not focus on coverage criteria, instead they select every test case that cause a modified program to produce different output than its original version.
