Internet applications testing automation through probabilistic-network programming

The paper considers the programming technology, which allows partially automate the testing of Internet applications. It allows you to develop a system of testing, as an expert systems. The testing system developing based on the proposed probabilistic-network approach. It allows to implement adaptive testing system, to achieve complete descriptions, improve the reliability of testing and reduce development time. Also this paper describes the ways of automatically generating elements of probabilistic networks by recording an expert tester´s actions and convert a probabilistic network elements in to UML diagrams. The paper contains example how automate functional testing of Web applications through its interface using probabilistic-network, despite that it contains some known and unknown defects.
