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)
Atwo-point BVAmeans testing both thelower and upper boundary valuesof each partition.The correct selection{7,8,21,22,29,30}includes:
