ISTQB Agile Tester Practice Test

The procedure to derive and select test cases based on an analysis of the specification, without reference to its internal structure, is accurately described by the term "black-box test design technique." This approach focuses on evaluating the functionality of the software based solely on the requirements and specifications, treating the application as a "black box" where the internal workings are not known or considered during testing.

Testers using black-box techniques assess inputs and expected outputs, ensuring that all functional requirements are met according to the specifications. This is particularly beneficial in agile testing environments where requirements may evolve, as it allows for straightforward validation of features against user stories without delving into the underlying code or architecture.

Other terms like white-box or gray-box involve knowledge of the internal structure. White-box testing requires insight into the internal code and design, while gray-box combines both black-box and white-box approaches. Static test design techniques relate to reviewing artifacts without executing the system, which differs from the active testing that black-box techniques involve. Thus, the definition and practice of black-box testing align perfectly with the described procedure.
