System Integration Testing:

System Integration Testing is based on black box testing techniques and is dependent on the specifications presented by the customer. It is used to validate an application’s accuracy and completeness in a ‘real life’ stimulation scenario which occurs once the application has been fully integrated. Interaction with a Graphical User Interface occurs to analyze the results.

Systems Integration Testing is widely used and most types of testing can be done under this way of testing. For example, functional, regression, load performance, stress, security, compatibility and user interface testing.
