Methods and Techniques for the Testing of AI-Based Systems

A transportation company has a fleet containing three delivery-vehicle types. The vehicles travel at varying speeds: slow, medium, and fast. To optimize scheduling, the company has developed an AI-based program that plans vehicle routes using records from medium-speed vehicles traveling to selected destinations. The test team applies this data in metamorphic testing to assess the accuracy of the AI route planner’s estimated travel times against the actual routes and times.

Which option describes the next phase of metamorphic testing?

Explanation

A metamorphic relation specifies how an expected result changes when an input is changed. Holding the route constant while substituting faster and slower vehicles creates follow-up test cases whose travel times should vary predictably with vehicle speed. Comparing actual arrival times with those derived expectations verifies the relation without requiring an independent exact travel-time oracle.
