Testers run a long weekend of simulated demand through a bike-share rebalance agent that learns from a reward. Monday’s routing no longer matches Friday’s. What testability problem is that?
Select an answer to reveal the explanation.
Short Explanation
A bike-share rebalance agent that learns from a reward, then Monday's routing no longer matches Friday's, is an adaptive system that may change during testing or because of the testing. The SUT can move while the suite runs. It is not locked.
Full Explanation
Adaptive systems are harder to test because the SUT can move while the suite runs. Treating it as locked, as Chapter 6 A/B, or as an oracle-only issue misses that movement.
