Step-by-Step Solution
Solution:
Step 1: Identify coverage goals
We want to cover edge cases and different input groups systematically.Step 2: Match techniques to goals
Boundary value analysis covers edges (1 and 100), equivalence partitioning divides inputs into groups.Step 3: Evaluate options
Use boundary value analysis for edges and equivalence partitioning for input groups. combines both techniques, improving coverage best; others are incomplete or random.Final Answer:
Use boundary value analysis for edges and equivalence partitioning for input groups. -> Option BQuick Check:
Combine boundaries + partitions = best coverage [OK]
Quick Trick: Combine boundary and group tests for full coverage [OK]
Common Mistakes:
- Relying on random or single-value tests
- Ignoring input group diversity
- Testing only multiples or arbitrary subsets
