What is the main idea behind equivalence partitioning as a data coverage criterion?

To test only the maximum and minimum values of the input domain

To divide the input domain into classes where all values in a class are expected to be treated the same by the system

To test every possible input value in the domain

To select test cases based on the likelihood of failure

What does the mutation score measure in the context of evaluating test selection effectiveness?

The number of lines of code in the model

The percentage of requirements covered by the test suite

The number of test cases that failed during execution

The percentage of mutated versions of the system that are detected by the test suite

A team has a large state machine model for an order processing system. They have a requirement document with 50 functional requirements. The team wants to use their MBT tool to automatically select a subset of test cases that ensures every requirement is covered by at least one test. What must be in place in the model for the tool to perform this selection?

A high number of test cases generated from the model

A set of boundary values for each input field

Traceability links between model elements and the requirements

A risk assessment for each model element

A team is testing a model for a simple calculator. The model has a decision point that checks if a divisor is zero. The team wants to ensure that the 'divide by zero' error path is tested. Which type of selection criterion is most directly applicable to ensure this specific path is exercised?

Data coverage (equivalence partitioning)

Structural coverage (branch coverage)

Why might a tester combine multiple selection criteria, such as structural and requirement-based criteria?

To eliminate the need for test oracles

To increase the number of test cases without any additional benefit

To reduce the need for test data generation

To achieve a more balanced test suite that covers both the model's structure and the system's requirements

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 33 practice questions to prepare you well beyond it.
