If a decision table has 3 conditions each with 3 possible states, how many unique test cases will it have?
medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate total combinations
Each condition has 3 states, so total combinations = 3 * 3 * 3 = 27.Step 2: Confirm test cases count
Each combination is a test case, so total test cases = 27.Final Answer:
27 -> Option BQuick Check:
Test cases = 3^3 = 27 [OK]
Quick Trick: Multiply states per condition for total cases [OK]
Common Mistakes:
- Multiplying incorrectly
- Using addition instead of multiplication
