Actual exam question for ISTQB's ISTQB-CTFL exam
Question #: 86
Topic #: 1

Which of the following options is correct with respect to the differentiation of black-box techniques, white-box techniques, and experience-based testing?

A. Experience-based testing is an extension of black-box test techniques, since experience-based test techniques also do not require knowledge about the source code. B. Experience-based testing can complement white-box and black-box test techniques well or can be used if the basic principles for these test techniques are lacking. C. The coverage items can be specified in advance, e.g., coverage of statements, states or checklists, for all three of the categories mentioned above. D. Black-box test techniques are based on requirements, white-box tests on source code. Therefore, black-box test techniques are always performed at higher test levels (e.g. system and acceptance level) and white-box test techniques at lower test levels.
