Why is it important to combine different test types across test levels?

To ensure that only one test type is used at each level.

To reduce the total number of test cases needed.

To achieve comprehensive coverage of quality characteristics and detect different types of defects.

To eliminate the need for regression testing.

A test manager is planning the test strategy for a large, safety-critical system. The system has strict reliability requirements, and the team must ensure that all code is thoroughly exercised. The budget is limited, so the manager must choose the most efficient combination of test types and levels. Which approach is most appropriate?

Perform only non-functional testing at the system level

Perform all test types at every test level

Perform functional testing at the system level and structural testing at the component level

Perform only structural testing at the component level

Part of the Domain 2: Testing Throughout the Software Development Lifecycle 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 19 practice questions to prepare you well beyond it.
