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:

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.

Test execution involves running test cases and documenting results. Test logs (A) provide evidence of executed tests, failures, and actual outcomes. Automated test scripts (B) are part of test implementation, test plans (C) belong to test planning, and test conditions (D) are identified during test analysis.

Testing and debugging are separate but related activities. Testing executes the software to identify failures that result from defects (A). Debugging is the developer's responsibility and involves finding the cause of a failure (defect), analyzing it, and fixing the defect. The ISTQB syllabus explicitly differentiates these activities. Testing does not modify the software, whereas debugging does.
