A team is testing a state machine with a loop that can be executed many times. They apply the all-transitions criterion, which requires each transition to be executed at least once. However, they are concerned that a fault only occurs when the loop is executed more than once. What should they do to increase fault detection?

Stick with all-transitions coverage

Use a stronger criterion, such as all-loop-paths coverage

A team is testing a model of a temperature control system. They want to ensure that test cases cover the boundary values of the temperature range (e.g., 0°C, 100°C, and just above/below these values). Which type of test selection criterion are they applying?

Data criterion (boundary value analysis)

Given a state machine with 5 states and 8 transitions, a team applies the all-transitions criterion. They generate test cases that together execute all 8 transitions. What can they conclude about the test suite?

All states are necessarily visited

All pairs of transitions are covered

A team is defining test selection criteria for a model. They want to ensure that the selected test cases are traceable to specific requirements and also cover all critical transitions. What is the best way to define the criteria?

Use only all-transitions coverage

Combine requirement-based and all-transitions criteria

Use only requirement-based coverage

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 23 practice questions to prepare you well beyond it.
