Decision table: which rule is not tested yet?
QuizMediumAsked in: Accenture, Infosys, Wipro
A decision table lists each combination of conditions as a rule (a column) with its expected result. The discount rules are:
| Rule | R1 | R2 | R3 | R4 |
|---|---|---|---|---|
| Member? | Yes | Yes | No | No |
| Total 1,000 or more? | Yes | No | Yes | No |
| Discount | 15% | 5% | 5% | 0% |
A tester has three tests: a member with an order of 1,200; a member with an order of 800; a non-member with an order of 1,500. Which rule is not covered?
- R4: a non-member with a total below 1,000, expecting 0%
- R1: a member with a total of 1,000 or more
- R3: a non-member with a total of 1,000 or more
- None: three tests are enough for four rules
