Consider a function that accepts an integer input from 5 to 15 inclusive. Which of the following test inputs is NOT a valid boundary value test case?
medium📝 Predict Output Q13 of Q15
Step-by-Step Solution
Solution:
Step 1: Identify boundary values and just outside values
Boundaries are 5 (min) and 15 (max). Just outside are 4 and 16.Step 2: Check which input is not a boundary or just outside value
Inputs 4, 5, and 15 are boundary or just outside values. 10 is a normal middle value, not a boundary test case.Final Answer:
10 -> Option AQuick Check:
Boundary tests exclude middle values like 10 [OK]
Quick Trick: Exclude middle values; test edges and just outside only [OK]
Common Mistakes:
MISTAKES- Including middle values as boundary tests
- Ignoring values just outside boundaries
- Confusing valid inputs with boundary inputs
