Questions tagged [black-box-testing]

"Black box" testing tests a device, program, application, etc., as a whole. Inputs are provided and the results monitored. The internal workings of the tested item are not relevant and may be unknown. "Functional testing" is a type of "Black box testing", but not all "black box" tests have to be "functional".
