Which of the following is the correct way to apply equivalence partitioning for an input field that accepts ages from 18 to 60?
ATest ages 17, 18, 30, 60, 61
BTest ages 18, 30, 60 only
CTest ages 0, 18, 60, 100
DTest ages 18, 19, 20, 21
Step-by-Step Solution
Solution:

  1. Step 1: Identify equivalence partitions

    Partitions are: below valid range (<18), valid range (18-60), above valid range (>60).

  2. Step 2: Select test values from each partition

    Choose one value from each: 17 (below), 18 and 60 (edges of valid), 30 (inside valid), 61 (above).

  3. Final Answer:

    Test ages 17, 18, 30, 60, 61 -> Option A

  4. Quick Check:

    Test one from each partition [OK]
Quick Trick: Pick one value from each input group including edges [OK]
Common Mistakes:
  • Testing only valid values
  • Ignoring boundary values
  • Testing too many values inside one partition
