The system is treated as a black box whose conduct can be observed, but whose sexual structure is unknown.* colour box testing= unit testing unit of measurement testing incremental testing of classes as they are implemented in order to ensure that they function properly. Testing can be white box testing where the tests are developed based on the units implementation, or gray box testing where tests are developed based wholly on a methods specification Computer Science Terms try out -- DefinitionsComputer Science TermsComposite structure the size of a typical software system implies that it must be broken down into manageable pieces of thisComposition the process of building a system using simpler parts or componentsAbstraction the process of ignor ing details irrelevant to the problem at hand and emphasizing essential ones.
