Reveal correct answer
Correct answer: A
Explanation
There are three equivalence partitions: {…, 17}, {18, …, 65}, and {66, …}.
The boundary values are 17, 18, 65, and 66. In the three-point boundary value analysis, for each boundary, we need to test the boundary and both its neighbors, so:
For 17, we test 16, 17, 18.
For 18, we test 17, 18, 19.
For 65, we test 64, 65, 66.
For 66, we test 65, 66, 67.
Altogether, we need to test 16, 17, 18, 19, 64, 65, 66, and 67.
Thus:
a) Is correct.
b) Is not correct.
c) Is not correct.
d) Is not correct.
