Why is Boundary Value Analysis considered more effective than random testing for input validation?

ABecause it tests every possible input value exhaustively

BBecause it focuses on edge cases where errors are most likely to occur

CBecause it ignores boundary values and tests only valid inputs

DBecause it requires less planning and is faster to execute

Step-by-Step Solution

Solution:

Step 1: Understand the goal of Boundary Value Analysis
BVA targets edge cases where software often fails, improving defect detection.
Step 2: Compare with random testing approach
Random testing does not focus on edges and may miss critical boundary errors.
Final Answer:
Because it focuses on edge cases where errors are most likely to occur -> Option B
Quick Check:
BVA targets edge errors = Because it focuses on edge cases where errors are most likely to occur [OK]

Quick Trick: Edges catch more bugs than random inputs [OK]
