Abstract

Model-based testing (MBT) of software systems is considered and well-known MBT methods and tools are reviewed. These methods make it possible to automate procedures performed by software test engineers and significantly increase the quality of testing software systems. The MBT technology, its components, and main tools are described. A list of problems arising in using MBT is compiled. A symbolic approach that makes it possible to solve some of existing MBT problems and the Generic Trace Generator based on the symbolic approach are presented. This tool was developed at the V. M. Glushkov Institute of Cybernetics. The symbolic approach is extended for the first time as a result of addition of the test execution stage that considerably improves the MBT technology.
