public Set intersection (Set s1, Set s2) // Effects: If s1 or s2 is null throw NullPointerException // else return a (non null) Set equal to the intersection // of Sets s1 and s2 Characteristic: Validity of s1 - s1 = null -s1 = {} -s1 has at least one element Characteristic: Relation between s1 and s2 -s1 and s2 represent the same set -s1 is a subset of s2 - s2 is a subset of s1 -s1 and s2 do not have any elements in common
Answer the following questions for the method intersection() depicted in the attached image.
Does the partition “Validity of s1” satisfy the completeness
property? If not, give a value for s1 that does not fit in any
block.
Does the partition “Validity of s1” satisfy the disjointness
property? If not, give a value for s1 that fits in more than one
block.
Does the partition “Relation between s1 and s2” satisfy the
completeness property? If not, give a pair of values for s1 and
s2 that does not fit in any block.
Does the partition “Relation between s1 and s2” satisfy the
disjointness property? If not, give a pair of values for s1 and s2
that fits in more than one block.
If the “Base Choice” criterion were applied to the two partitions
(exactly as written), how many test requirements would result?
