To analyze an open system with a typical "black box approach", only the behavior of the stimulus/response will be accounted for, to infer the (unknown) box. The usual representation of this "black box system" is a data flow diagram centered in the box.
Black-box testing, sometimes referred to as specification-based testing, [1] is a method of software testing that examines the functionality of an application without ...
The social constructivist conception of black boxing doesn't delineate the physical components hidden inside an apparent whole; rather, what is black-boxed are associations, various actors from which the box is composed. Opening the hood of an electric car, for example, reveals only mechanical components.

A common approach is to start from measurements of the behavior of the system and the external influences (inputs to the system) and try to determine a mathematical relation between them without going into many details of what is actually happening inside the system; this approach is called black box system identification.
Software testing can often be divided into white-box and black-box. These two approaches are used to describe the point of view that the tester takes when designing test cases. A hybrid approach called grey-box that includes aspects of both boxes may also be applied to software testing methodology. [31] [32]
Orthogonal array testing is a systematic and statistically-driven black-box testing technique employed in the field of software testing. [1] [2] This method is particularly valuable in scenarios where the number of inputs to a system is substantial enough to make exhaustive testing impractical.
The CTM is a black-box testing method and supports any type of system under test. This includes (but is not limited to) hardware systems , integrated hardware-software systems, plain software systems , including embedded software , user interfaces , operating systems , parsers , and others (or subsystems of mentioned systems).
