System Integration In Software Testing

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.

System integration in software testing.

It is testing conducted on a complete integrated system to evaluate the system s compliance with its specified requirement. Sit consists initially of the process of assembling the constituent parts of a system in a logical cost effective. 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. 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.

The purpose of this level of testing is to expose faults in the interaction between integrated units. The system on which sit is performed may have different hardware parts different software parts or both hardware and software. What is system integration testing. System integration testing sit is the overall testing of the whole system which is composed of many sub systems.

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. Difference between system testing and integration testing. 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 testing process ensures that all subcomponents are integrated successfully to provide expected results. The integration and integration testing must adhere to a building plan for the defined integration and identification of the bug in the early stages.
