A project has a model with many requirements, but some requirements are more critical than others. The team has a limited test budget and must ensure that all requirements are covered, but they want to prioritize the critical ones. Which approach best achieves this?

Use only risk-based criteria to prioritize critical requirements

Use stochastic criteria to generate a random set of tests

Combine requirement-based and risk-based criteria to prioritize critical requirements while ensuring all are covered

Use only requirement-based criteria to cover all requirements equally

A team needs to generate a large number of test cases quickly to stress-test a model's robustness. They do not have specific requirements or risk assessments. Which selection method is most suitable?

Coverage-based selection targeting 100% path coverage

A team is testing a complex state machine with a large number of states and transitions. They have a limited test budget and need to achieve a high level of confidence in the system's behavior. They are considering using random selection to generate a large number of test cases quickly. However, they are concerned that random selection may not cover all critical branches. What is the best approach to address this concern?

Use only random selection and rely on the large number of test cases to cover critical branches

Use only branch coverage criteria to generate test cases

Use risk-based criteria to select test cases

Use random selection to generate a large number of test cases and then measure branch coverage to identify gaps

Part of the Selection Criteria for Test Case Generation domain, which makes up ~19% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~5–8 in this domain), expect 1–1 from this objective — we provide 28 practice questions to prepare you well beyond it.

A regulatory audit requires that every functional requirement be linked to at least one test case in the MBT suite. The team has a model with hundreds of transitions, but only a subset directly implements the documented requirements. Which selection criterion should be applied to satisfy the audit?
