What BEST describes how tools can support the practice of Model-Based Testing (MBT)?
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
B.
MBT tools can generate different levels of load on the system under test simulating predefined usage models for trial system
C.
MBT tools can be used to generate large sets of distinct execution threads which can be saved and used as test cases
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
The Answer Is:
D
This question includes an explanation.
Explanation:
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.
