How to perform integration testing in Quality Engineering?

Submitted by: Administrator

Integration testing is black box testing. Integration testing focuses on the interfaces between units, to make sure the units work together. For integration testing we ensure that all units testing of the each component is performed earlier. Integration testing begins only after the unit testing. The purpose of integration testing is to ensure different components of the application interact with each other. So that, components work as per the customer requirements. Test cases are developed with the purpose of exercising the interfaces between the components. Integration testing is considered complete, when actual results and expected results are same.
