Integration testing is done to check how different components actually interact with each other and how well they perform as a system. This test is performed after unit testing, where each component is individually tested. The main aim of integration testing is to check the compatibility and compliance of various components, to reveal the faults, and to check the data flow in the system. Acceptance testing is done to verify if the product developed meets the business requirements. It is a type of black-box testing where the primary focus is on the end-user requirements.
