What statement is an accurate advantage of Model-Based Test Automation?

• A. It eliminates the need for any testing.
• B. You can save effort because you can create models by scanning your SUT.
• C. It makes end-to-end tests harder to read.
• D. It cannot reuse models.

Answer: (B)

Model-based test automation leverages a model of the system under test to drive test design and execution. The strongest advantage is saving effort by creating models from the actual SUT, such as by scanning the application to discover components, actions, and data flows. This lets you generate multiple tests from one model, keeps tests aligned with the real behavior, and makes maintenance easier as changes in the SUT can be reflected by updating the model. The other statements aren’t accurate: testing isn’t eliminated, MBTA can improve readability through clear, high-level models, and models can be reused across tests and scenarios.
