Editing White-box testing (section)

== Modern view ==
A more modern view is that the dichotomy between white-box testing and black-box testing has blurred and is becoming less relevant. Whereas "white-box" originally meant using the source code, and black-box meant using requirements, tests are now derived from many documents at various levels of abstraction. The real point is that tests are usually designed from an abstract structure such as the input space, a graph, or logical predicates, and the question is what level of abstraction we derive that abstract structure from.<ref name=introtest>{{cite book |last1=Ammann |first1=Paul |last2=Offutt |first2=Jeff |author-link2=Jeff Offutt |date=2008 |title=Introduction to Software Testing |publisher=Cambridge University Press |isbn=978-0-521-88038-1 |url=http://cs.gmu.edu/~offutt/softwaretest/ }}</ref> That can be the source code, requirements, input space descriptions, or one of dozens of types of design models. Therefore, the "white-box / black-box" distinction is less important and the terms are less relevant.{{citation needed|date=October 2015}}
