System Integration In Software Testing

System integration testing sit is a high level software testing process in which testers verify that all related systems maintain data integrity and can operate in coordination with other systems in the same environment.

System integration in software testing.

System integration testing sit is the overall testing of the whole system which is composed of many sub systems. Sit consists initially of the process of assembling the constituent parts of a system in a logical cost effective. The testing process ensures that all subcomponents are integrated successfully to provide expected results. Difference between system testing and integration testing.

The system on which sit is performed may have different hardware parts different software parts or both hardware and software. It is testing conducted on a complete integrated system to evaluate the system s compliance with its specified requirement. However an integrator or integration tester must have the programming knowledge unlike system tester. Integration testing is a level of software testing where individual units components are combined and tested as a group.

System integration testing sit involves the overall testing of a complete system of many subsystem components or elements. The purpose of this level of testing is to expose faults in the interaction between integrated units. System integration testing sit is the type of software testing that is carried out to perform the overall testing of a complete system that consists of many integrated components. The system under test may be composed of hardware or software or hardware with embedded software or hardware software with human in the loop testing.

Test drivers and test stubs are used to assist in integration testing. The main objective of sit is to ensure that all software module dependencies are functioning properly and the data integrity is preserved between distinct modules of the whole system.
