System Testing is the testing of a complete and fully integrated product. For large Information Systems, software is typically just one component of a large set of system hardware/software components that is ultimately interfaced with other system components. System Testing is accomplished with a series of different tests whose sole purpose is to exercise all components of the complete computer-based system.
There are two categories of Software Testing: White Box Testing and Black Box Testing
White box testing is the testing of the internal workings or code of a software application. In contrast, black box testing involves the external workings of the system from the user’s perspective.
Testing the fully integrated applications including external peripherals in order to check how components interact with one another and the whole system is called End-to-End testing.
