There are different types of Integration Testing, few are listed below:

Big Bang:

• In this approach, all or most of the developed modules are coupled together to form a complete software

system or major part of the system and then used for integration testing.

• The Big Bang method is very effective for saving time in the integration testing process.

Bottoms Up:

• An approach to integration testing where the lowest level components are tested first, then used to

facilitate the testing of higher level components.

• The process is repeated until the component at the top of the hierarchy is tested. The main advantage of

the Bottom up is easy to find bugs.


• It is the procedure where the top integrated modules are tested and the branch of the module is testing

step by step till end of the related module. In Top down it is easy to find the missing branch link.
