    System integration testing is testing performed when two systems, generally presumed stable themselves, are integrated with one another. For example, this could be when an inventory management system is integrated with a sales accounting system. Each system feeds into the other.

    The goal of systems integration testing is to ensure that the data crossing the boundary between systems is received, stored and used appropriately by the receiving system. Until integration begins, testing of the isolated systems is done on mocked or replayed data and not on "live" data. Integration testing is the final step before customer acceptance testing.

    What is User Acceptance Testing?

    User Acceptance Testing is often the final step before rolling out the application.

    Usually the end users who will be using the applications test the application before ‘accepting’ the application.

    This type of testing gives the end users the confidence that the application being delivered to them meets their requirements.

    This testing also helps nail bugs related to usability of the application.

    User Acceptance Testing – Prerequisites:

    Before the User Acceptance testing can be done the application is fully developed.

    Various levels of testing (Unit, Integration and System) are already completed before User Acceptance Testing is done. As various levels of testing have been completed most of the technical bugs have already been fixed before UAT.

    User Acceptance Testing – What to Test?

    To ensure an effective User Acceptance Testing Test cases are created.

    These Test cases can be created using various use cases identified during the Requirements definition stage.

    The Test cases ensure proper coverage of all the scenarios during testing.

    During this type of testing the specific focus is the exact real world usage of the application. The Testing is done in an environment that simulates the production environment.

    The Test cases are written using real world scenarios for the application

    User Acceptance Testing – How to Test?

    The user acceptance testing is usually a black box type of testing. In other words, the focus is on the functionality and the usability of the application rather than the technical aspects. It is generally assumed that the application would have already undergone Unit, Integration and System Level Testing.

    However, it is useful if the User acceptance Testing is carried out in an environment that closely resembles the real world or production environment.

    The steps taken for User Acceptance Testing typically involve one or more of the following:

    .......1) User Acceptance Test (UAT) Planning

    .......2) Designing UA Test Cases

    .......3) Selecting a Team that would execute the (UAT) Test Cases

    .......4) Executing Test Cases

    .......5) Documenting the Defects found during UAT

    .......6) Resolving the issues/Bug Fixing

    .......7) Sign Off

    System Integration Testing (SIT) services ensure that individual modules, product set-ups, batch operations, basic reporting functionality and key interfaces of an application-under-test (AUT) work well. SIT determines the degree of conformance of an AUT with the Functional Specifications Document / Technical Specifications Document.

    Where as,

    User Acceptance Testing (UAT) is the final hurdle in the deployment of any software solution, which covers Business process flow, Interfaces, Alerts, Reports and Batch processing.

    Both are steps included in Functional Testing phase.

    AT is nothing but User Acceptance Testing where we test the

    application at customers' site to check whether the system

    is working fine or not.This is the last phase of testing.

    SIT is System integration testing.It is one of the phases of

    testing where you perform System testing and Integration

    testing combined together on a regular basis.It a different

    process altogether for which specific tools are there.

    One is testing of the operation prior to release. The other is testing the operation after release.
