A major release is approaching, and the team has made significant changes to the system and updated the MBT model accordingly. They need to ensure that the entire system still works as expected. What is the most appropriate regression strategy?

Run only the test cases that cover the changed parts of the model.

Run the full regression suite derived from the updated model.

Run a random sample of the test suite to save time.

Run only the test cases that failed in the previous release.

A team has a large MBT suite that takes 10 hours to run. They are introducing a new feature that affects only a small part of the system. The team wants to get fast feedback on the new feature while still ensuring no regressions in the affected area. What is the most efficient regression strategy?

Run the full suite only once a week to save time.

Run the full 10-hour suite every time a change is made to the new feature.

Run only the test cases for the new feature and skip regression testing.

Run a selective regression suite covering the new feature and all model elements that interact with it, and schedule the full suite for a nightly run.

A team has a large state model for an embedded device. They need to run a nightly regression suite, but the full set of generated test cases takes over 12 hours to execute. The product owner wants faster feedback on critical features. Which scheduling strategy best balances coverage and execution time?

Prioritize test cases based on model coverage and business risk, and schedule the highest-priority subset for the nightly run.

Randomly select a subset of test cases each night to vary coverage.

Run the full test suite every night and accept the 12-hour execution time.

Execute only the test cases that failed in the previous run.

A team has generated a large number of test cases from a model. They need to execute them in a CI/CD pipeline, but the pipeline has a limited time window. What is the best way to prepare the test cases for execution in this constrained environment?

Run all generated test cases and extend the pipeline time window.

Run the test cases in parallel on multiple agents to fit the time window.

Select a subset of test cases that achieve the required model coverage within the time window, and schedule them to run.

Skip test execution in the pipeline and run tests manually.

In model-based testing, what is the primary goal of a selective regression strategy?

To re-execute all test cases in the suite

To generate new test cases from the updated model

To re-execute only the test cases affected by the changes

To skip regression testing entirely

Different Kinds of Test Execution CT-MBT Practice Questions (Page 5)

Part of the MBT Test Implementation and Execution domain, which makes up ~16% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 31 practice questions to prepare you well beyond it.
