Model-Based Testing relies on __________ to represent the behavior of the system under test.

Model-Based Testing relies on models to represent the behavior of the system under test. These models can take various forms, such as state diagrams, finite state machines, or flowcharts. The use of models in testing allows for more efficient test design, execution, and maintenance, as the tests are derived from the explicit representation of the system's behavior. This approach enhances test coverage and helps in identifying potential issues early in the development process.
