integration testing stands for testing the data flow
between the module.In integration testing we come across
two types and they are
1.Incremental integration testing and
2.non-incremental integration testing.

Incrmental integration testing

In incremental integration testing we are going to
incrementally add the module and test the data flow.

In incremental integration testing we come across two types
and they are

a.Top down incremental testing and
b.Bottom up incremental testing

Top down incremental testing
Here we are incrementally adding the module from the top
and be sure that the module which we are adding is child of
previous one.

Bottom Up incremntal testing
Here we incrementally adding the module from the bottom
and be sure that the module which we adding is child of
previos one.

2. Non inremental integration testing

Here if we are not able to identfy which is child and
which is parent i.e unable t identify the root cause
analysis of the product.At that time we will collect all
the module and start testing the module at a time.

Answer / nitin sharma

Combining two already tested units ina compaonent and check
the interface between them is integration testing
It's of three types
1.Top-Down:It is integration approach When Main module is
ready and sub module are not ready then we use stubs to test
2.Bottom-Up:It is integration approach in which When main
module is not ready and sub module are ready then we use
drivers to test
3.Big Bang: In this approach all are ready modules we
integrate them nad then test
