Step-by-Step Solution
Solution:
Step 1: Understand boundary value analysis requirements
BVA requires testing boundaries and values just outside boundaries to catch edge errors.Step 2: Analyze given test inputs
Inputs 100, 150, 200 test boundaries and middle but miss values 99 and 201 just outside boundaries.Final Answer:
It misses testing values just outside the boundaries -> Option CQuick Check:
Missing outside boundary values = It misses testing values just outside the boundaries [OK]
Quick Trick: Always test just outside boundaries too [OK]
Common Mistakes:
- Ignoring values just outside boundaries
- Assuming boundary values alone are enough
- Testing unrelated invalid inputs
