==Purpose==

The purpose of '''Integration testing''' is to verify functional, performance and reliability [[requirements]] placed on major design items. These "design items", i.e. assemblages (or groups of units), are exercised through their interfaces using [[Black box testing]], success and [[error case]]s being simulated via appropriate parameter and data inputs. Simulated usage of shared data areas and [[inter-process communication]] is tested, individual [[subsystem]]s are exercised through their input interface. All [[test case]]s are constructed to test that all components within assemblages interact correctly, for example, across procedure calls or process activations.and is done after the testing single module i.e. unit testing

The overall idea is a "building block" approach, in which verified assemblages are added to a verified base which is then used to support the '''Integration testing''' of further assemblages.
