Analysis:
Model-Based Testing (MBT) tools are designed to generate test cases based on models of the system under test.
D: MBT tools can generate test cases using a model of the system under test, but they cannot reduce the very large number of possible paths that can be generated in the model:
* MBT tools create test cases from models, but managing the large number of possible test paths generated remains a challenge. These tools help automate the generation of test cases but often require
* additional strategies to handle the complexity and volume of test paths.
Explanation of Incorrect Options:
* A. MBT tools can help by generating a model of the system under test, based on the test results derived from both systematic and experience-based testing techniques:
* MBT tools generate test cases from existing models, not create models from test results.
* B. MBT tools can generate different levels of load on the system under test simulating predefined usage models for trial system:
* This describes performance testing tools rather than MBT tools.
* C. MBT tools can be used to generate large sets of distinct execution threads which can be saved and used as test cases:
* While partially true, it does not capture the essence of the challenge with the large number of possible paths.
