The integration testing is a software development process
which program units are combined and tested as groups in
multiple ways. (A UNIT IS DEFINED AS THE SMALLEST TESTABLE
PART OF AN APPLICATION ) It happens after unit testing and
before system testing.
The purpose of integration testing is to verify functional,
performance and reliability requirements placed on major
design items. Also to verify units interact correctly and
the hardware configuration items and software configuartion
items are interacted adequately.
There are four approaches for integration testing as below:
1.big bang 2.top-down 3.bottom-up 4.sandwich
But only top-dwon and bottom-up are the major ways of
carrying out an integration test.
Bottom-up integration testing begins with unit testing
followed by higher level combinations of units called modules.
In the top-down integration testing, the highest-level
modules are tested first and progressively lower-level
modules are tested after that.
So the main advantage of bottm-up approach is that bugs are
more easily found with top-down approach ,it is easier to
find the missing branch link and show the whole software
process to user early.
