Software System Integration Testing

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.

Software system integration testing.

What is system integration testing. Sit consists initially of the process of assembling the constituent parts of a system in a logical cost effective. It is an end to end user perspective testing intended to find defects in the software system. 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. The testing process ensures that all subcomponents are integrated successfully to provide expected results. Integration testing is conducted to evaluate the compliance of a system or component with specified functional requirements. 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. 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. System integration testing sit involves the overall testing of a complete system of many subsystem components or elements. Difference between system testing and integration testing.

System testing is testing of the software application as a whole to check if the system is complaint with the user requirements. Integration testing is a level of software testing where individual units components are combined and tested as a group. System integration testing sit is the overall testing of the whole system which is composed of many sub systems.
