The ever-increasing architectural complexity of software systems makes testing a very serious challenge for both developers and consumers. It is extremely important for consumers to make sure that the system is working according to the pre-defined requirements and expectations before going to its actual operation.

The main objective of the dissertation is to classify and analyze the existing approaches for functional testing of the integrated information systems, to identify their weaknesses in use in defense systems and to offer new improved models and algorithms applicable to the testing of integrated defense systems.
