System Integration In Software Testing

Test drivers and test stubs are used to assist in integration testing.

System integration in software testing.

Integration testing is a level of software testing where individual units components are combined and tested as a group. 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 testing sit involves the overall testing of a complete system of many subsystem components or elements. System integration testing sit is the overall testing of the whole system which is composed of many sub systems.

Difference between system testing and integration testing. It is testing conducted on a complete integrated system to evaluate the system s compliance with its specified requirement. 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. The system on which sit is performed may have different hardware parts different software parts or both hardware and software.

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. However an integrator or integration tester must have the programming knowledge unlike system tester. Sit consists initially of the process of assembling the constituent parts of a system in a logical cost effective. What is system integration testing.

System integration testing is defined as a type of software testing carried out in an integrated hardware and software environment to verify the behavior of the complete system. The purpose of this level of testing is to expose faults in the interaction between integrated units.
