   What is a common disadvantage of fully manual test case generation compared to automated generation?

   • AIt cannot be used for safety-critical systems.
   • BIt always produces test cases that are less effective than automated ones.
   • CIt is highly dependent on the individual tester's skills and can be time-consuming for large systems.
   • DIt requires a formal model of the system, which is often unavailable.

   Why might an organization choose a lower degree of automation (e.g., manual generation) even when a model is available?

   • ABecause manual generation always produces higher quality test cases than automated generation.
   • BBecause manual generation is always faster than automated generation.
   • CBecause automated generation is only possible for small models, not large ones.
   • DBecause the team lacks the necessary tooling skills, or the cost of acquiring and maintaining a test generator is not justified.

   A startup is developing a novel user interface with no existing model. The requirements are still evolving, and the team is exploring different design options. They need to create a few exploratory test cases to validate the basic functionality and user flows. The team has no MBT tools and limited budget. Which approach is most appropriate?

   • AFully manual test generation, because the requirements are unstable and there is no model to automate from.
   • BSemi-automated test generation, using a tool to generate random inputs.
   • CFully automated test generation, because it will save time even without a model.
   • DPurchase an expensive MBT tool to create a model from the UI automatically.

   In the context of model-based testing, what does the term 'degree of automation' refer to?

   • AThe percentage of test execution steps that are run automatically by a test execution tool.
   • BThe level of detail in the model used for test generation, such as state diagrams versus decision tables.
   • CThe extent to which test cases are generated by a tool rather than manually created by a tester.
   • DThe number of test cases generated per unit of time, regardless of how they are produced.

   In which scenario is fully manual test case generation most likely to be used?

   • AWhen the project has a large budget and wants to reduce human effort to a minimum.
   • BWhen the system is simple, requirements are well understood, and the tester's experience is the primary source of test ideas.
   • CWhen the test environment is fully virtualized and test data is generated automatically.
   • DWhen a formal model of the system under test is available and the team wants to maximize coverage.
