Test generation for time critical systems: Tool and case study

Generating timed test sequences by hand is error-prone and time consuming, and it is easy to overlook important scenarios. The paper presents a tool based on formal methods that automatically computes a test suite for conformance testing of time critical systems. The generated tests are selected on the basis of a coverage criterion of the specification. The tool guarantees production of sound test cases only, and is able to produce a complete covering test suite. We demonstrate the tool by generating test cases for the Philips Audio Protocol.
