Evolution of UniTESK Test Development Technology.
The paper considers almost 20-year evolution of UniTESK test development technology in ISP RAS and its future perspectives. It presents the basic principles of UniTESK: using formal software contracts as a base of test adequacy criteria and test oracle construction, uniform test suite architecture helping to organize various kinds of testing in one framework, interleaving semantics used to specify asynchronous interactions, and using extended FSM models derived from contracts and coverage criteria to generate test sequences automatically. The paper then summarizes experience of using UniTESK in large test development projects for software and hardware systems, including telecommunication protocols, basic and standard interfaces of operating systems, microprocessor units. Several directions of future technology development are depicted, all intended for higher scalability of test suites constructed: parallelization of test execution for large test suites, using more efficient techniques of asynchronous behavior analysis, automated merging of different bugs representing the same faults, automatic extraction of compact and most substantial bug description (including short demonstration scenarios) from huge data obtained as a result of long and complex automated test execution.
