A developer is testing a non-safety-related function that processes user input. The function has a switch statement with 5 cases and a default case. The team wants to achieve high branch coverage. How many test cases are needed to cover all branches of the switch statement?

Ten test cases: two for each case to test both true and false outcomes.

Five test cases: one for each case, but not the default.

Six test cases: one for each case and one for the default.

Two test cases: one for any case and one for the default.

A team is working on a non-safety-related system and wants to integrate white-box testing into their continuous integration (CI) pipeline. Which tool-related approach is most appropriate?

Do not use any tools in CI because they slow down the pipeline.

Run a coverage tool as part of the CI pipeline to measure coverage on every build.

Use a static analysis tool instead of a coverage tool in CI.

Run the coverage tool only once before release to save time.

In a non-safety-related system, what is the primary purpose of applying white-box testing techniques?

To verify that the system meets user requirements from an end-user perspective

To replace the need for black-box testing in all projects

To prove that the software is free of all defects before release

To ensure that the internal structure and logic of the code are exercised and validated

What is a primary role of tools in supporting white-box testing for non-safety-related systems?

Automating the execution of test cases and measuring code coverage

Generating user documentation automatically

Replacing the need for testers to design test cases

Managing the project schedule and resources

Part of the Domain 2: White-Box Test Techniques domain, which makes up ~19% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–15 in this domain), expect 1–2 from this objective — we provide 19 practice questions to prepare you well beyond it.
