Incremental Integration Testing:-

When unit testing is accomplished, computer programmer executes the integration testing. This is the procedure of confirming the interfaces and interaction among the components or modules. In the time of integration there are many approaches utilized by the computer programmers, incremental testing approach is one of them.  

In the incremental integration testing approach, the computer programmers integrate or combine the components or modules individually applying stubs or drivers to expose the issues or defects. This testing technique is recognized as the incremental integration testing.There is also one integration testing approach is available that is big bang. In the big bang approach all the modules are merged into one attempt.

Incremental Integration Testing Methodologies:- There are mainly three types of incremental integration testing methodologies available. These are as--

•  Top Down Integration
•  Bottom Up Integration
•  Functional Incremental Integration

Characteristics Of Incremental Integration Testing :-

There are many characteristics of the incremental integration testing. Few of them are mentioned below --

•  Every module or components supplies an explicit role to play in the project in the organization.
•  Every module has distinctly determined dependencies few of which can be understood only at the run time.
•  The main advantage of the incremental integration testing is the issues are established initially in the small meetings when it is comparatively simple to identify the root cause for the same.
•  There is also a disadvantage that is, it takes long time since stubs and drivers have to be made for executing these tests.
