t. e. 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 peering into its internal structures or workings. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.
t. e. In science, computing, and engineering, a black box is a system which can be viewed in terms of its inputs and outputs (or transfer characteristics), without any knowledge of its internal workings [1][2]. Its implementation is "opaque" (black). The term can be used to refer to many inner workings, such as those of a transistor, an engine ...

The term "black box" was a World War II British phrase, originating with the development of radio, radar, and electronic navigational aids in British and Allied combat aircraft. These often-secret electronic devices were encased ...
Code coverage tools can evaluate the completeness of a test suite that was created with any method, including black-box testing. This allows the software team to examine parts of a system that are rarely tested and ensures that the most important function points have been tested. [ 35 ]
Rogers' criterion for whether a voting machine is a black box is strict—you must be able to sense that it works correctly as you use it. A somewhat weaker criterion is sometimes accepted, based on whether the public is allowed to examine the mechanism, in a modern context, both the source code and hardware. [ 4 ]
v. t. e. In software development, functional testing is a form of software system testing that verifies whether software matches its design. Generally, functional testing is black-box meaning the internal program structure is ignored (unlike for white-box testing). [1] Functional testing can evaluate compliance to functional requirements.
