Property Testing

Definition

Property testing is a subfield of theoretical computer science focused on determining if a given object possesses a certain property, or is “far” from possessing it, by examining only a small, constant number of its elements. This technique provides a highly efficient way to approximate properties of large datasets or complex structures without inspecting every component. In cryptographic contexts, it can verify aspects of a protocol’s output or a data structure’s integrity with minimal computational overhead. It offers probabilistic guarantees about the presence or absence of a characteristic.
