Abstract

We will first give a brief introduction to a versatile modeling environment that allows the early validation of system specifications by a test-driven agile simulation approach. The main focus of our paper is on providing techniques for automated test case generation relying on statistical usage models. Based on the open source software R for statistical computing and graphics the easy to handle test case generation and analyzing TestPlayer© tool was developped. Starting from customer-specific graphical Markov chain usage models test cases are automatically generated and visualized by highlighting selected nodes and arcs in the model. In addition, various metrics and corresponding diagrams offer analytical techniques to assess the quality of the derived test suite.
