Fundamentals of testing AI-based systems · Question 49 of 60

A self-learning pricing system was accepted with a set of expected results. After a few weeks, many of these tests fail although the system works well. What is the reason?

1 answer is correct. Hard

1. A Self-learning systems have no test oracle problem, so the tests are written incorrectly
2. B The test environment is misconfigured and therefore delivers deviating results
3. C In self-learning systems, the "correct" behavior changes, so old expectations become invalid
4. D The system is defective and must be reset immediately to its accepted state
