The purpose of this chapter is to introduce the objectives of integration testing and the techniques used. Integration testing occurs when two or more modules, components, or subsystems are combined to form a new subsystem or a system. During the integration testing phase it is generally assumed that the components being integrated have been tested independently. Hence, the focus in this phase is on errors that may exist due to communication among components being integrated. Often, when many components ...
