A mountain-rescue radio-triage model emits an urgency score. Dispatchers cannot name one correct number for a garbled call. Testers agree a band and a tolerance. Which oracle workaround is that?
Select an answer to reveal the explanation.
Short Explanation
Dispatchers cannot name one correct urgency number for a garbled call. Testers agree a band and a tolerance. That is an output-boundary oracle: ranges, distributions, limits, or tolerances when a single expected value does not exist. A missing single number is not a reason to skip testing.
Full Explanation
When a single expected value does not exist, testers use a band and a tolerance. Demanding one number, opening Chapter 6 derivation, or skipping testing misses that workaround.
