System Testing aims to bring out defects that are inherent in the entire system rather than in individual components. This test is named the System Testing because this testing is functional and validates the system requirements. System Testing is carried out by systematically testing the whole system against the system use cases. The system must be used in a manner as close as possible to the way in which it will eventually be utilized. System Testing should normally be executed several times until the whole system functions as intended and meets with the completion criteria of the test.
Each module is tested and integrated and then the test is carried out for the entire system. When all the modules are integrated and tested without bugs, the system will ready for implementation. System testing is therefore the testing conducted on a complete, integrated system to evaluate the systems compliance with its specified requirements. System testing does not presuppose the knowledge of the software inner design of the code or its logic. System Testing involves all the software components that have been successfully integrated.
While the purpose of integration testing is to detect any inconsistencies between the software units that are integrated together and the hardware, System testing is a more limiting type of testing; it seeks to detect defects within the system as a whole. System testing is actually carried out on the entire system against the Functional Requirements Specification and the System Requirement Specification.
Moreover, the System testing is a testing phase where the focus is to have almost a destructive attitude and test not only the design, but also the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds defined in the software/hardware requirements specification. In system testing, the mission is finding and reporting software defects. This implies that the system passes the test only if the whole group of its test cases have passed testing. In contrast, in acceptance testing a testing mission and pass/fail criteria can be defined differently from the system testing.
