To provide the relation between two or more modules those 
are already cinstructed or under construction to check out 
whether those are working or not.

Combing the modules in the application after developing all
the modules and after conducting unit testing. During
integration testing we are combing the modules and test the
data flow between the modules generally it is conducted by
the developers those who are involved in developing the
modules

All individual unit are integrated and tested is called 
integrated testing

Initially Unit testing is conducted i,e Verifying the logic 
of a single program is called unit testing and also we can 
call as testing a single program.Once Unit testing is 
completed those tested units(program) are intergrated and 
we call it as a module.Then those modules are tested to 
validate that after integrating all the programs that 
module is functioning properly or not and we also call this 
as Component testing also.Once all the  modules are tested 
then those modules are again integrated,To check those 
interconnections are working properly or not we conduct 
integration testing.For Example in Gmail application 
Sentitems,Inbox.... are different modules and developed 
independently.After completely developing those modules we 
will integrate them and conduct integration testing so that 
it is functioning as expected or not, for this we will 
approaches Such as TOP Down,Bottom up,Big Bang,Hybrid 
approach.

If I am wrong please correct me.

Combined/integrated all the modules and we test exact 
navigation from module to another module.
The purpose of integration testing is to ensure distinct 
components of the application still work in accordance to 
customer requirements.

all the elements(modules)are connected to each other and 
after that we are going for testing

integration testing:-all under control condition of 
application's both the function works correctly or not to 
check that functionality is called integration testing.
thank you.
