A company is developing a safety-critical system. They have a very tight budget for testing. The team is considering MBT to improve test coverage. They have a small team with limited modeling experience. What is the most important trade-off to consider?

The need for high coverage and traceability versus the cost and effort of model development and maintenance.

The cost of MBT tooling versus the cost of manual test design.

The risk of missing defects versus the risk of introducing defects in the model.

The potential for improved coverage versus the cost of training the team on MBT.

How does model-based testing (MBT) differ from scripted testing?

MBT is manual, while scripted testing is automated.

MBT requires a formal model, while scripted testing requires a test plan.

MBT uses models to generate test cases, while scripted testing uses predefined test scripts.

MBT is only applicable to unit testing, while scripted testing is for system testing.

A team is using MBT to generate tests for a new feature. They have created a model and generated a set of test cases. They want to ensure the tests cover all the important paths in the model. What should they do?

Add more test cases manually to the generated set.

Execute the tests and see which ones fail.

Manually review the generated tests to see if they cover all paths.

Use a coverage criterion in the MBT tool to guide test generation.

A team maintains a legacy system with no automated tests. They are about to start a 3-month project to add a new billing module. The team has no model-based testing experience, and the project timeline is fixed. The system's requirements are well-documented and stable. What should the team do?

Avoid MBT for this project, because the team's lack of experience and the fixed timeline pose a high risk of delays and cost overruns.

Use MBT only for the legacy system, since it has no tests and would benefit most from automated test generation.

Use MBT for the new module, but only if the team can get external MBT consultants to build the models and generate tests.

Adopt MBT for the new module, investing in training and tooling, because the stable requirements make it a good fit.

Which statement best defines model-based testing (MBT)?

Testing that uses models of the test team's past experience to prioritize test cases.

Testing that relies on a model of the test environment to simulate network conditions.

Testing that uses a model of the system's user interface to automate test execution.

Testing based on models of the system's environment, behavior, or structure that are used to generate or select test cases.
