Integration Testing
It
is the phase of software testing in which individual software modules
are combined and tested as a group. It follows unit testing and
precedes system testing. takes as its input modules that have been
checked out by unit testing, groups them in larger aggregates, applies
tests defined in an Integration test plan to those aggregates, and
delivers as its output the integrated system ready for system testing.
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 cases being
simulated via appropriate parameter and data inputs. Simulated usage of
shared data areas and inter-process communication is tested, individual
subsystems are exercised through their input interface. All test cases
are constructed to test that all components within assemblages interact
correctly, for example, across procedure calls or process activations.
The
overall idea, is the "building block" approach in which verified
assemblages are added to a verified base which is then used to support
the Integration testing of further assemblag

Main Purpose is to test just Interface betn two Unit tested Modules.

Objective of Integration testing is to make sure that the interaction
of two or more components produces results that satisfy functional
requirement. In integration testing, test cases are developed with the
express purpose of exercising the interface between the components.
