BlackBoxTechniken
BlackBoxTechniken refers to methods and practices that analyze, design, or interact with systems whose internal structure or implementation is not visible or disclosed. The guiding assumption is that only inputs, outputs, and externally observable behavior are available, while the inner workings are treated as a black box. The term is used across disciplines such as software engineering, control theory, data science, and cryptography.
In software engineering, black-box techniques include black-box testing and interface-driven development, where evaluation and validation are
Advantages include applicability when internals are unknown, proprietary, or too complex to model directly, and scalability
Common methods comprise input–output testing, fuzz testing, metamorphic testing, surrogate modeling, observational experiments, and conformance checks
