SXMtool - A tool for stream X-machine testing

One of the great benefits of using a Stream X-machine (SXM) to specify a system is its associated testing method. Under certain test conditions, this method produces a test suite that can determine the correctness of the implementation under test (IUT). However, the size of the test suite is generally very large; the manual test suite generation is very complex and error-prone. With the more and more application for SXM in test area, developing the automatic support tool is urgent. The paper introduces the algorithm of obtaining the key values and sets, and develops the tool SXMtool which supports the editing of SXM models, automatic generation of SXM test suite. An example of using the SXMtool is then given to present its function.
