Use Scenario 1 “Happy Tomatoes” (from the previous question).
Using the Boundary Value Analysis (BVA) technique (in its two-point variant), identify the set of input values that provides the HIGHEST coverage.
{7,8,21,22,29,30}
{7,8,22,23,29,30}
{6,7,8,21,22,29,31}
{6,7,21,22,29,30}
Comprehensive and Detailed In-Depth Explanation:
Boundary Value Analysis (BVA) focuses on test cases at the edges of partitions because defects often occur at boundaries. The temperature ranges are:
≤7 (Too cold → W)
[8-21] (Standstill → X)
[22-29] (Ideal → Y)
≥30 (Too hot → Z)
A two-point BVA means testing both the lower and upper boundary values of each partition.
The correct selection {7,8,21,22,29,30} includes:
7 → Boundary of Too Cold (W)
8 → Lower boundary of Standstill (X)
21 → Upper boundary of Standstill (X)
22 → Lower boundary of Ideal (Y)
29 → Upper boundary of Ideal (Y)
30 → Lower boundary of Too Hot (Z)
This ensures maximum boundary coverage.
