Integration testing will be done based on System Design so identifying which are all the areas the 2 modules communicating with each others how the data has been transferred, based on that we have to develop test cases and test the integration (communication) between modules.

To be more clear about what integration is , i ll give an exampleSuppose if we take an example as gmail, there we find different modules like inbox,Lable etc... suppose if we are doing integration testing for diff modules ie, inbox and label, in label we create a folder like "my resume" and u have the resume in ur inbox. When u move that mail to the folder created in label, That mail should go to that particular folder....... This is nothing but integration testing. After integration of two modules it should work accordingly...Anybody can correct me if i am wrong..............

Intergration testing is technique used for integrate the hole module.

Integration Testing purely depends on how the system is designed, which helps to determine the interdependency between each module.
When we know how individual modules depend on each other, we can do integration testing of two or more modules depending upon their interdependency.

initially write the testcase for the individual module after that make that two module is placed and make a application,that is main one,in that two sub module are they.

for example:In gmail account,when user click on the inbox,it goes to inbox page,the page which is open that is one module,same like user click on the draft,sent..etc,after that
what happen all are integrate to make a one page ie gmail home

Its purely based the importance of module, Eg : we have 2 modules called A & B. B module have relation with A module we need to first test with A module. Also we can to top down or bottom up approach. Before that we need to refer the SRS to get the info about the testing modules.

Integration testing mainly meant for writing test cases for integrated components not individuals and the interface between two componets/applications. If your application has only two components, A&B, no need to worry about the integration of components and its test cases as it would be taken care by system test. This case we need to focus on test cases on interface between A&B and how its communicating together. But if we have another module C and that will integrate later, need to focus on test cases for both integrating A&B (A&B alone as a system) and interface too.

Integration testing is done between the module, means what will be the impact of one functionality to others.

Ex:- suppose IN Gmail inbox is one module and sent box is one module. If we sent any mail then it must show in the sent item this the integration testing.
