Mention few advantages of performing Integration testing?

◼ Each module in software development is developed by different programmers whose approach and understanding may differ from module to module. Integration testing becomes important to ensure that these developed modules when assembled works in unity.

◼ There are various instances in which there’s creeping requirements or few requirement changes suggested while the software was in development phase and these changes wouldn’t have been implemented as expected or

even might have been missed at unit testing and hence integration testing becomes a necessity.

◼ We also need to validate the interface of the software modules in parallel with the databases and in such cases, this is important.
