Given the input field accepts numbers 1 to 100, which test inputs represent valid equivalence partitions?
A[50, 75, 100]
B[0, 1, 50, 100, 101]
C[-1, 0, 101]
D[1, 50, 100]
Step-by-Step Solution
Solution:
  1. Step 1: Define partitions

    Partitions are: below valid (<1), valid (1-100), above valid (>100).
  2. Step 2: Check which inputs cover all partitions

    [0, 1, 50, 100, 101] includes 0 (below), 1 and 100 (edges valid), 50 (inside valid), 101 (above).
  3. Final Answer:

    [0, 1, 50, 100, 101] -> Option B
  4. Quick Check:

    Inputs cover all partitions [OK]
Quick Trick: Include below, inside, and above range values [OK]
Common Mistakes:
MISTAKES
  • Missing values outside valid range
  • Testing only inside range
  • Ignoring boundary values
