Acceptance testing

In engineering and its various subdisciplines, acceptance testing is black-box testing performed on a system (e.g. software, lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. In some engineering subdisciplines, it is known as functional testing, black-box testing, release acceptance, QA testing, application testing, confidence testing, final testing, validation testing, usability testing, or factory acceptance testing.
