What characterizes Model-Based Test Automation?

• A. A performance testing framework.
• B. During testing, models are created and contain the information needed for steering the testing.
• C. It replaces the need for any test design.
• D. It is a subset of manual testing.

Answer: (B)

Model-based test automation centers on building abstract representations of the system and its expected behavior. These models describe the possible actions, data flows, state changes, and acceptance criteria. During testing, the models are created and contain the information needed to steer the testing—driving which steps to take, which inputs to use, and what results to verify. This approach enables automated test generation and systematic exploration of the application, with the model serving as the guide for test execution.

This explains why this option is the best fit: the driving artifact is the model itself, not a separate framework for performance, nor a claim that there’s no need for test design, and not simply a subset of manual testing.
