Question: How to write Integration Testcases?

Answer: In integration testing you need to write test cases for the Interface between the modules, For eg: if you are writing test cases for the integration of 3 modules M1, M2 and M3. you need to write the test cases for the individual behaviour of M1, M2 and M3. After that you need to write the test cases for their combinations like when we integrate M1 and M2, to test how will be the behaviour of M1+M2 and to verify the interface between them. in the same way for the combinations of M2, M3 M3,M1 and M1, M2 and M3. Here when we are integrating different modules, u need to write test cases to verify mainly the interface between the modules and to verify wheather the behaviour is meeting the requirements. The Integration test cases will be in the same format of normal testcases, but with some more additional fields like, Modules integrated.
