    Unit testing is to test the changes done for the program and will be done by the developer..

    Regression testing is to make sure that the changes done for the program didn't broke any existing functionality..

    hi

    good

    Unit Testing=>

    A process for verifying that software, a system, or a system component performs its intended functions.

    Unit transactions are tested against their own specifications and design documents.

    Integration Testing =>

    An orderly progression of testing in which software elements, hardware elements or both are combined and tested until the entire system has been integrated.

    Integration tests deal mainly with the testing of cross-application process chains in addition to transactions and business processes. The process models and the test cases derived from these form the basis of these tests.

    Regression Testing->

    Sucid Function also fully automates SAP regression testing to deliver iterative verification of SAP as the system evolves over time, both during major implementations and during the years between these major projects as the company's business processes and SAP applications continually change.

    This is theoretically possible with other products, but practically speaking it's not done due to the time, cost and complexity constraints involved. Sucid Function makes the maintenance of a comprehensive SAP test suite quite practical by utilizing Sucid Transport, a Sucid technology written completely in ABAP and embedded into the SAP system under test, to deliver these unique capabilities, as well as the Sucid Appliance and Sucid Client. SAP regression testing is absolutely critical to ensuring business continuity over time.

    thanks
